acinclude.m4: New macro MPFR_CHECK_PRINTF_SPEC looking for support of the "%jd", "%qd", and "%td" conversion specifications in printf and gmp_printf.

configure.in: Call MPFR_CHECK_PRINTF_SPEC when we can link against a suitable gmp library and run test programs at compile time, otherwise (for instance, when cross compiling), everything is enable by default.
vasprintf.c: Disable support for length modifiers not supported by libc's printf ('j' and 'q' for this time).
tests/tprintf.c, tests/tfprintf.c: Disable tests for length modifiers not supported by gmp_printf ('j', 'q', and 't' for this time).
