I've been informed that parsing of Solaris ld -V output doesn't work
with Solaris sed. The problem is that the alternation used since
[build] Cleanup Solaris linker version checks
https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00068.html
isn't recognized by /usr/bin/sed and /usr/xpg4/bin/sed which can only
handle BREs. This means that all features dependent on ld version
checking aren't supported anymore.
I hadn't recognized this before since I've been using GNU sed
exclusively. While Illumos sed could work around this by using sed -E
instead, which enables ERE support, this option isn't recognized by
Solaris sed.
Fortunately, the fix is simple: the alternative ld -V output format
handled since the patch above never made it into a non-beta version of
Solaris, and never will, so I'm just removing this again.
Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11. Installed for mainline now; will backport to
the gcc-9 and gcc-8 branches after some soak time.
For good measure, I've also run Solaris bootstraps with /usr/bin in
front of /usr/gnu/bin, but this issue was the only difference.
