That would rather defeat the point of ensuring that GCC's definition of 
intmax_t agrees with the target's when a target which didn't previously 
have one acquires one.  The use of inttypes.h, a header only required of 
hosted but not freestanding implementations, is deliberate because of 
pre-C99 systems that have <inttypes.h> but not <stdint.h>.

wchar_t-1.c and wint_t-1.c used to be xfailed on systems lacking 
<wchar.h>, something similar could be used on systems lacking inttypes.h 
so when they gain the header the compilation XPASSes but the test for 
excess errors still fails if the type is incorrect.
