use alias attribute only for elf platforms

Browse Source 
It was reported that clang on OSX doesn't support alias attribute. Most
likely because of executable format limitations.

New code limits use of alias to gcc-compatible compilers on elf
platforms (various gnu and *bsd systems). Elf format is known to support
aliases.
