MMX raises the following build failure on i686:

gsm0610_rpe.c: In function 'gsm0610_rpe_encoding':
gsm0610_rpe.c:132:5: error: invalid 'asm': invalid constraints for operand
     __asm__ __volatile__(
     ^~~~~~~

+Subject: [PATCH] configure.ac: fix AVX, SSE and MMX options
+
+AVX, SSE and MMX options are broken since
+https://github.com/freeswitch/spandsp/commit/87a900c70df73e128a5926587047f529105f5f64
+
+For example, when the user enables SSE, it will also enable MMX and the
+user can't disable MMX
