[PATCH] gcc-cross-canadian: Install gcc/g++ wrappers for musl

["Alejandro Hernandez Samaniego" <alhe@linux.microsoft.com>]

From: Khem Raj <raj.khem@gmail.com>

gcc needs -mmusl option to be passed in SDK since we ship crossdk compiler
configured for glibc by default, this helps in creating correct
compiler defaults for musl based SDK compilers

[YOCTO #13459]

(From OE-Core rev: e6fbac7aeabe00d8fb734992012dd629a8527b25)
