Fix standalone ich_descriptor_tool compilation with MinGW and DJGPP
TARGET_OS as well as EXEC_SUFFIX were only set when called via the
main makefile and even then __USE_MINGW_ANSI_STDIO was not set
for MinGW.
While at it, also replace the hardcoded gnu_printf printf format
attribute with __MINGW_PRINTF_FORMAT which is set according to
__USE_MINGW_ANSI_STDIO respectively.
