Description of the problem / feature request:

building bazel from source for the first time and getting below error: gcc: error: unrecognized command line option ‘-fuse-ld=–enable-gold=yes’

the issue is unix_cc_configure.bzl where it is trying to determine whether ‘-fuse-ld=gold’ is set. It is going through each line to find first line that contains the word ‘gold’. Unfortunately, it found below line and return flag as ‘–enable-gold=yes’: x86-64.rhel.6 --enable-gold=yes --enable-tls --enable-rpath --enable-shared --enable-languages=c,c++,objc,fortran

I saw the same issue, was able to dance around it with this patch:

I fixed the issue in the rules_cc repo so you can use that instead of the snapshot of it that is distributed with Bazel (so you don’t have to wait for Bazel release).

And TBH, I just forgot to fix it in Bazel. Will do that this week.
