headers: default 32-bit x86 to Windows XP
The x86_64 multilib toolchain shares one header tree between its 64-bit
and 32-bit targets. Keep the configured mingw-w64 default for x86_64 and
other architectures, but preserve w64devkit's Windows XP default when
the compiler targets i686. An explicit user definition still takes
precedence through the existing outer guard.
