Thanks for fixing it! I did test it, and it was working on my machine,
both with and without the new build flag:
Running /home/bluca/git/binutils-gdb/ld/testsuite/ld-bootstrap/bootstrap.exp ...
Running /home/bluca/git/binutils-gdb/ld/testsuite/ld-bpf/bpf.exp ...
I imagine this is because I was running 'make check' from the ld/
directory? I took '$srcdir' and 'fgrep' from existing scripts in other
tests in ld/testsuite. Anyway, the important thing is that it's all
good now.
Thanks again!
