build: add systemtap's sys/sdt.h as depends 
The sys/sdt.h header is required to build Bitcoin Core with Userspace
Statically Defined Tracing support. Systemtap version 4.5 (May 2021)
is used as the most recent version 4.6 (Nov 2021) fails to build.
See e.g. https://sourceware.org/git/?p=systemtap.git;a=commit;h=1d3653936fc1fd13135a723a27e6c7e959793ad0

As Systemtap itself is not needed, the build steps (configure and
make) are skipped. We require fewer build dependecies and don't
waste time building depends we don't end up using. However, the
configure step would normally processes sys/sdt-config.h.in. The
resulting sdt-config.h defines _SDT_ASM_SECTION_AUTOGROUP_SUPPORT
(either 0 or 1 to indicate whether the assembler supports "?" in
.pushsection directives). For now, we assume all currently used
assemblers supports this feature and remove the check from the
sys/sdt.h header file in a patch.

.NOTPARALLEL :
# Pattern rule to print variables, e.g. make print-top_srcdir
print-%: FORCE
@echo '$*'='$($*)'
# When invoking a sub-make, keep only the command line variable definitions
# matching the pattern in the filter function.
#
# e.g. invoking:
# $ make A=1 C=1 print-MAKEOVERRIDES print-MAKEFLAGS
#
# with the following in the Makefile:
# MAKEOVERRIDES := $(filter A=% B=%,$(MAKEOVERRIDES))
#
# will print:
# MAKEOVERRIDES = A=1
# MAKEFLAGS = -- A=1
#
# this is because as the GNU make manual says:
# The command line variable definitions really appear in the variable
# MAKEOVERRIDES, and MAKEFLAGS contains a reference to this variable.
#
# and since the GNU make manual also says:
# variables defined on the command line are passed to the sub-make through
# MAKEFLAGS
#
# this means that sub-makes will be invoked as if:
# $(MAKE) A=1 blah blah
MAKEOVERRIDES := $(filter V=%,$(MAKEOVERRIDES))

# Previously, we directly invoked the well-known programs using $(shell ...)
# to construct build_id_string. However, that was problematic because:
#
# 1. When invoking a shell, GNU Make special-cases exit code 127 (command not
# found) by not capturing the output but instead passing it through. This is
# not done for any other exit code.
#
# 2. Characters like '#' (from these programs' output) would end up in make
# variables like build_id_string, which would be wrongly interpreted by make
# when these variables were used.
#
# Therefore, we should avoid having arbitrary strings in make variables where
# possible. The gen_id script used here hashes the output to construct a
# "make-safe" id.
#
# Also note that these lines need to be:
#
# 1. After including {hosts,builders}/*.mk, since they rely on the tool
# variables (e.g. build_CC, host_STRIP, etc.) to be set.
#
# 2. Before including packages/*.mk (excluding packages/packages.mk), since
# they rely on the build_id variables

# $PATH is not preserved between ./configure and make by convention. Its
# modification and overriding at ./configure time is (as I understand it)
# supposed to be captured by the AC_{PROG_{,OBJ}CXX,PATH_{PROG,TOOL}} macros,
# which will expand the program names to their full absolute paths. The notable
# exception is command line overriding: ./configure CC=clang, which skips the
# program name expansion step, and works because the user implicitly indicates
# with CC=clang that clang will be available in $PATH at all times, and is most
# likely part of the user's system.
#
# Therefore, when we "seed the autoconf cache"/"override well-known program
# vars" by setting AR=<blah> in our config.site, either one of two things needs
# to be true for the build system to work correctly:
#
# 1. If we refer to the program by name (e.g. AR=riscv64-gnu-linux-ar), the
# tool needs to be available in $PATH at all times.
#
# 2. If the tool is _**not**_ expected to be available in $PATH at all times
# (such as is the case for our native_cctools binutils tools), it needs to
# be referred to by its absolute path, such as would be output by the
# AC_PATH_{PROG,TOOL} macros.
#
# Minor note: it is also okay to refer to tools by their absolute path even if
# we expect them to be available in $PATH at all times, more specificity does
# not hurt.
