This line (119) defines the answer, which you see on the screen, when the
configure script is running. The following line
AC_MSG_RESULT(yep!!!)
would result in
...
checking for memmove... yes
checking whether the compiler supports cpuid... yes
checking whether the compiler supports 3Dnow... yep!!!
checking whether the compiler supports MMX... yes
...
but changes nothing else.

Do you get a
MMX cpu detected.
3Dnow cpu detected.
message, if you start a OpenGL program ?? If yes, the library was
compiled correctly (with -DUSE_MMX_ASM and -DUSE_3DNOW_ASM in CFLAGS in
the src/X86 directory).
You are right, the styles in configure.in and the Makefile.am in
src/X86 are a bit confusing and not really straightforward.
But it should work.
