[PATCH 5/6] strace: Define own sigmask macro if not defined already in signal.h

[Khem Raj <raj.khem@gmail.com>]

This is required especially on uclibc systems where BSD compatible
obsolete functions are disabled by kconfig. Therefore we check
if the macro is undefined then we define it. Therefore eglibc/glibc
builds should work as they use to.

+sigmask is a macro which is dropped if BSD compatibility is
+not enabled. So we check if the macro does not exist then
+we define it to __sigmask
