x86/headers: Fix (old) header file dependency bug in uapi/asm/sigcontext32.h
Mikko Rapeli reported that the following standalone user-space header does not compile: #include <asm/sigcontext32.h> Due to undefined 'struct __fpx_sw_bytes' which is defined in asm/sigcontext.h. The following header order works: #include <asm/sigcontext.h> #include <asm/sigcontext32.h> and that's probably how everyone's been using these headers for the past decade or so, but it's a legit header file dependency bug, so include asm/sigcontext.h in sigcontext32.h to allow it to be built standlone.
