Fix building for Linuxbrew (#575) 

Linuxbrew is a fork of Homebrew on Linux.
In which, the `gcc --version` will report "homebrew".
Therefore, the current code will incorrectly set OSXPORT_COMPILER
under such environment, which results to the following compiling errors:

gcm.cpp:823: Error: too many memory references for `add'
gcm.cpp:824: Error: too many memory references for `pxor'
gcm.cpp:825: Error: ambiguous operand size for `shr'
gcm.cpp:826: Error: too many memory references for `movzx'
gcm.cpp:827: Error: too many memory references for `add'
gcm.cpp:828: Error: too many memory references for `pxor'
gcm.cpp:829: Error: too many memory references for `movzx'
gcm.cpp:830: Error: too many memory references for `add'
gcm.cpp:831: Error: too many memory references for `pxor'
gcm.cpp:832: Error: ambiguous operand size for `add'
gcm.cpp:833: Error: ambiguous operand size for `sub'

Fix this problem by checking IS_DARWIN before setting OSXPORT_COMPILER.
