Title: Fix sim makefile so it works on mac

These changes include a path separator fix and the removal of --gc-sections which causes ld failures, and is not needed on a pc.

This patch also changes how a compiler is selected. The makefile will now select the system compiler , which should work fine
under mingw and linux.
