Portfile for GCC 16 has:

MacPorts' log file of my build of GCC 16 has:
:debug:patch Executing reinplace: /usr/bin/sed {s|^do-compare =|do-compare =
/usr/bin/true|g}
</opt/local/var/macports/build/gcc16-f5979bbe/work/gcc-16.1.0/Makefile.in

So it's obvious that the if in Portfile evaluates to true, the configure
arguments are changed and then the post-patch action is applied.
Could this be the cause of the make/ln failure? Should I try a new build
without that post-patch action?
Are there more options to pass to GNU Make 3.81 to help find out why it is not
making the other symlinks?
