[yocto] gcc enable-languages

[Javi Roman]

I had the same issue. The problem seems the variable FC (Fortran
Compiler) is not properly setup (in meta/conf/bitbake.conf).

The libtool-cross recipe shows QA problems with wrong include paths
when uses x86_64-poky-linux-gfortran tests.

This workaround works for me:

recipes-devtools/gcc
└── gcc-cross_4.7.bbappend
recipes-devtools/libtool/
└── libtool-cross_2.4.2.bbappend

With:

$ cat recipes-devtools/gcc/gcc-cross_4.7.bbappend
FORTRAN = ",fortran"

$ cat recipes-devtools/libtool/libtool-cross_2.4.2.bbappend
export FC = "${CCACHE}${HOST_PREFIX}gfortran ${HOST_CC_ARCH}
--sysroot=${STAGING_DIR_HOST}"
