Take -DWX_PRECOMP out of GCC_PRAGMA_FLAGS and put it into its own PCH_FLAGS.

If -DNO_GCC_PRAGMA is included in GCC_PRAGMA_FLAGS (because the platform
always requires it) then it won't be duplicated in PCH_FLAGS, but if
the platform does not normally need -DNO_GCC_PRAGMA then the flag
will be included in PCH_FLAGS because PCH always requires it.
