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.
