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
