Andrew Hsieh 6c2d94dfcf Add __gnuc_va_list in stdio.h to stop gcc from generating include-fixed/stdio.h ...

When GCC is built bionic's stdio.h (among other headers) is fixed: __va_list
is replaced with __gnuc_va_list, and put in include-fixed/stdio.h,
unless stdio.h already contains __gnuc_va_list.  When GCC is later
used bionic's stdio.h is never included.

The problem in the context of NDK is that all 32-bit Android toolchain
are built with android-9 header and expect to work with all API levels
sometime with sustantially different stdio.h.

This CL stops GCC from generating include-fixed/stdio.h by putting
__gnuc_va_list in it.
