build: Fix shared lib linking for darwin with lld

Browse source 
libtool gets a false-positive from the warning produced by lld -single_module
because it is already the default and unneeded.

Skip the check unconditionally for Darwin linkers.

dnl Because it prints a verbose warning, lld fails the following check
dnl for "-Wl,-single_module" from libtool.m4:
dnl # If there is a non-empty error log, and "single_module"
dnl # appears in it, assume the flag caused a linker warning
dnl "-single_module" works fine on ld64 and lld, so just bypass the test.
dnl Failure to set this to "yes" causes libtool to use a very broken
dnl link-line for shared libs.
