[OE-core] [PATCH dylan & dora & master] image-mklibs: ensure sysroot is correctly set when calling gcc

[Nicolas Dechesne]

[YOCTO #2519]

When getting gcc from sstate, it is possible to get a gcc with a bogus
sysroot configuration, as discussed in [1] or in [YOCTO #2519].

mklibs script will eventually call gcc, so we need to make sure that it
provides gcc with the right sysroot location.
