[Bug target/35239] New: Build failure when host cc is GCC-2.95,3 or earlier

[gschafer at zip dot com dot au]

The build/bootstrap fails in driver-1386.c due to cpuid changes:

/tmp/ccWPtRYo.s: Assembler messages:

The older GCC apparently doesn't grok the asm syntax. More information in the
thread starting here:

Failing to build from 2.95.3 is quite serious so I suggest a high priority for
this one. Thanks.
