[PATCH v3 1/1] gfortran: update runtime dependencies

[<kai.kang@windriver.com>]

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

It fails to run both `gcc` and `gfortran` with errors:

| root@qemux86-64:~# x86_64-poky-linux-gcc a.c
| x86_64-poky-linux-gcc: fatal error: cannot execute 'as': posix_spawnp: No such file or directory

then add binutils which provides `as` to RDEPENDS of gcc.

libgfortran-dev provides libgfortran.spec which required by gfortran:

| root@qemux86-64:~# gfortran hello.f95
| gfortran: fatal error: cannot read spec file 'libgfortran.spec': No such file or directory

And gcc provides liblto_plugin.so:

| root@qemux86-64:~# gfortran hello.f95
| gfortran: fatal error: '-fuse-linker-plugin', but liblto_plugin.so not found
