[OE-core] [PATCH] Fix GCC 5.2 "_FOR_BUILD" and related variables

[Bystricky, Juro]

The patch works unmodified  (and solves mingw build problems) for gcc 4.9. as well,
providing gcc-4.9.inc is  patched the same way as gcc-5.2.inc

(However, this makes  the Makefile.in patch  status:

Upstream-Status: Pending 

incorrect for case of gcc 4.9.)
