cross-canadian: Put links in place for uclibc and musl
gcc-cross-canadian-<arch> is only built once. It needs to target all the different libcs, not just the currently selected one. This change ensures that if another libc is used, symlinks are present such that the compiler can be found. The base version is always assumed to be "glibc" with symlinks from musl and uclibc compiler names. This means gcc-cross-canadian is consistent regardless of which libc is selected when its build in multimachine builds. [YOCTO #8025] (From OE-Core rev: 83ead626c0da75edec2833ffb1a29011ec7b83d2) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
