[PATCH v3 1/1] glibc: fix fortran header file conflict for arm

[<kai.kang@windriver.com>]

From: Kai Kang <kai.kang@windriver.com>

There is a file conflict for arm when multilib enabled:

| Error: Transaction test error:
|   file /usr/include/finclude/math-vector-fortran.h conflicts between attempted installs of
    lib32-libc6-dev-2.39+git0+312e159626-r0.armv7at2hf_neon and libc6-dev-2.39+git0+312e159626-r0.cortexa72

Install math-vector-fortran.h to the gfortran default search directory
which is arch specific to avoid the conflict.
