[PATCH 3/3] perf trace: Decode architecture-specific signal numbers

[-- Attachment #1: Type: text/plain, Size: 1231 bytes --]

SIGSTKFLT is not defined on alpha, mips or sparc.
SIGEMT and SIGSWI are defined on some architectures and should be
decoded here if so.

Fixes: 8bad5b0abfdb ('perf trace: Beautify signal number arg in several syscalls')
