Looks like this breaks on AIX 4.3.3 :(

gl_CHECK_NEXT_HEADERS fails to find the absolute file name for
stddef.h, it finds the empty string and substitutes

#include ""

into the generated stdarg.h

It looks like gl_CHECK_NEXT_HEADERS fails for headers that do not
declare any functions. stdarg.h only defines macros :(
