[PATCH 1/3] gcc: Fix nonportable shell syntax in "test" and "[" commands [PR105831]

[Jonathan Wakely via Gcc-patches]

From: Michael Bäuerle <mi...@netbsd.org>

POSIX sh does not support the == for string comparisons, use = instead.

gcc/ChangeLog:

        PR bootstrap/105831
        * config/nvptx/gen-opt.sh: Use = operator instead of ==.
        * configure.ac: Likewise.
        * configure: Regenerate.
