relibc: mirror fresh libc to prefix and redoxer toolchain

Browse Source 
After cooking relibc, copy the freshly built libc.a and libc.so to both
the prefix toolchain and the redoxer toolchain (the latter is what
'make live' actually consumes for cross-recipe builds).

Without this, recipes that link against the dynamic libc.so see a stale
copy (no eventfd, no __fseterr, ...) and fail with 'undefined reference'
at link time. 'make prefix' does this sync via its sysroot rule, but
'make r.relibc' alone does not — covering both paths prevents the
first recipe that needs a new symbol from breaking the build.
