Remove configure tests for AVX support.
GCC added support for -mavx and -msse2avx in version 4.4. Thus the
configure tests for this support are obsolete, and this patch removes
them.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by this patch).

test.
