Here is the updated one, in which 'WORDS_BIGENDIAN' is checked to get
the host-endianness. This macro is used somewhere else in GDB, so looks
it is a right way.
Rebuild native GDB on x86-linux and cross build GDB for mingw32 target
respectively.

* ctf.c (ctf_save_metadata_header): Define macro
HOST_ENDIANNESS. Write HOST_ENDIANNESS to metadata.
(ctf_start) [USE_WIN32API]: Call mkdir with DIRNAME only.
[!USE_WIN32API]: Call mkdir with DIRNAME and mode parameter.
