Re: svn commit: r362987 - in head: contrib/bc usr.bin/gh-bc

The following is more informational than anything as far
as I'm concerned. But there may be implications that I'm
unaware of. (I sometimes experiment with toolchain use
to see what the current status is for such use.)

I attempted to build a system for 32-bit powerpc using clang
and binutils, building head -r363000 ( from -r363000 ). (This
was a cross build, amd64 -> powerpc.) It got a new type of
failure, compared to my past experience:

--- gh-bc.full ---
/usr/local/powerpc-unknown-freebsd13.0/bin/ld: /usr/bin/../lib/LLVMgold.so: error loading plugin: Cannot open "/usr/bin/../lib/LLVMgold.so"
cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** [gh-bc.full] Error code 1

Yep: /usr/lib/LLVMgold.so when -B/usr/local/powerpc-unknown-freebsd13.0/bin/
was in use.

I turns out that the link of gh-bc used -flto :
