    powerpc64: Fix syscall_cancel build for powerpc64le-linux-gnu [BZ #32125]

    In __syscall_cancel_arch, there's a tail call to __syscall_do_cancel.
    On P10, since the caller uses the TOC and the callee is using
    PC-relative addressing, there's only a branch instruction with no NOPs
    to restore the TOC, which causes the build error. The fix involves adding
    the NOTOC directive to the branch instruction, informing the linker
    not to generate a TOC stub, thus resolving the issue.
