The patch doesn't appear to fix the problem: while it does set
libc_cv_asm_avx512=no, I still get an error at "make check".

AFAICT, tst-auditmod10 is not conditional on asm_avx512.

/tmp/ccha40tw.s: Assembler messages:
/tmp/ccha40tw.s:47: Error: no such instruction: `vmovdqa64 %zmm0,-176(%rbp)'
/tmp/ccha40tw.s:51: Error: bad register name `%zmm0'
...
make[2]: *** [/build/elf/tst-auditmod10a.os] Error 1

Here is what AVX in my config.log looks like:

libc_cv_asm_avx512=no
libc_cv_cc_avx512=yes
libc_cv_cc_avx=yes
libc_cv_cc_sse2avx=yes


Please note: I am not complaining and could easily update my assembler,
if that's the right thing to do here.

For the record:

gcc --version
gcc (GCC) 4.9.0 20140309 (experimental)
...

gcc -Wa,--version -xc /dev/null
GNU assembler (GNU Binutils) 2.22.52.20120719
...
