This commit updates the gcc musl patches for gcc 4.7, 4.8 and 4.9 so
that the path to the dynamic linker encoded as "program interpreter"
in the generated binaries actually matches the symbolic link installed
by musl when building for mips soft-float.
Indeed, musl installs a symlink called ld-musl-mipsel-sf.so.1, but gcc
currently generates binaries that use /lib/ld-musl-mips.so as program
interpreter.
The fix is simply the one from
https://bitbucket.org/GregorR/musl-cross/commits/825219202365, i.e
adjust MUSL_DYNAMIC_LINKER in our musl gcc patches.
Thanks to these patches:
$ ./host/usr/bin/mipsel-linux-readelf -a ./target/bin/busybox
[...]
[Requesting program interpreter: /lib/ld-musl-mipsel-sf.so.1]
[...]
gcc 5.x doesn't need any fix because the musl patches already use the
right value.
Fixes bug #7562.

Now that we are always explicitly passing gcc_cv_libc_provides_ssp,
there is no longer any reason to modify the gcc configure/configure.ac
to take into account the musl case. When a musl toolchain is being
built, BR2_TOOLCHAIN_HAS_SSP is always 'y', and therefore
gcc_cv_libc_provides_ssp=yes is always passed when building
gcc-initial and gcc-final.
