    hurd: Fix unwinding over INTR_MSG_TRAP

    We used to use .cfi_adjust_cfa_offset around %esp manipulation
    asm instructions to fix unwinding, but when building glibc with
    -fno-omit-frame-pointer this is bogus since in that case %ebp is the CFA and
    does not move.

    Instead, let's force -fno-omit-frame-pointer when building intr-msg.c so
    that %ebp can always be used and no .cfi_adjust_cfa_offset is needed.
