Add compat/setenv.c, use in git.c.
There is no setenv() in Solaris 5.8. The trivial calls to setenv() were replaced by putenv() in a much earlier patch, but setenv() was used again in git.c. This patch just adds a compat/setenv.c. The rule for building git$(X) also needs to include compat. objects and compiler flags. Those are now in makefile vars COMPAT_OBJS and COMPAT_CFLAGS. Signed-off-by: E.
