libunwind: Link with libucontext on musl
Functions like unw_getcontext in libunwind call getcontext() which are not part of musl C library like glibc, however there is a supplimental library providing these functions called libucontext, therefore link libunwind with a static version of this library to resolve such symbols, this inturn helps packages needing libunwind, who look for certain APIs in libunwind during configure e.g. heaptrack (From OE-Core rev: 824c07d1cf2d1574dfe8f395af37479064782426) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
