Details:

The current gnutls 3.0.15 release contains assembly files in
lib/accelerated/x86/asm which are incompatible with i386/x86_64 darwin.
Minimal changes are required for these to properly compile on darwin...

1) Use the more portable .balign rather than .align (since i386/x86_64 darwin
doesn't support .align > 15).
2) Add underscore to global symbols (as well as _aesni_set_encrypt_key and
calls to it) using SYM macro.
3) Add TYPEF/TYPEO and SIZE macros to handle .type for @function/@object and
.size on darwin as is done in the FSF gcc libitm assembly files.
4) Add and :"#ifdef __linux__" on ".section .note.GNU-stack,"",%progbits"

With these change the accelerated assembly code is compiled at i386 and x86_64
on darwin10/11 and the resulting build passes the gnutls test suite.
