[PATCH] PR target/32787 (bootstrapping i386 with non-GCC compiler)

   GCC_VERSION is defined unconditionally by include/ansidecl.h, so the test
in config/i386/driver-i386.c to use cpuid.h only with GCC doesn't work,
causing failure to bootstrap with a non-GCC compiler on x86 platforms. This
patch fixes it by testing for __GNUC__ instead.

   The bug was reported for GCC 4.2.1 using Sun Studio 12 to bootstrap and
there's a similar failure when using OpenWatcom to bootstrap trunk.

   This patch is for trunk. I'll commit it as obvious once testing on
x86_64-unknown-linux-gnu finishes.
