    tests/libc: only build brk_test where libc provides sbrk
    
    Replace the exclusion list with an allowlist of the architectures
    whose libc exports brk/sbrk: amd64, i386, arm and powerpc.
    
    On aarch64, riscv and loongarch libc does not export those symbols
    and the test cannot run, so do not build it there. New architectures
    now default to not building the test unless brk support is added.
