#     selftests/powerpc: Fix compilation issue due to asm label
#     
#     We are using 'dscr_insn' as a label in inline asm to identify if a
#     SIGILL was generated by the mtspr instruction at that point. However,
#     with inline assembly, the compiler is still free to duplicate the asm
#     statement for optimization purposes, which results in the label being
#     defined twice with the error:
#             /tmp/ccerQCql.s:874: Error: symbol `dscr_insn' is already defined
#     
#     With different compiler versions, we may also see:
#             /tmp/ccJzLDlN.o:(.toc+0x0): undefined reference to `dscr_insn'
#     
#     Remove the use of the label in the inline assembly. Instead, just look
#     for the offending instruction in the signal handler.
#     
#     Fixes: d2bf793237b3 ("selftests/powerpc: Add test to verify rfi flush across a system call")
