Add option NO_FP_LIBC, which disables floating-point support in
*printf() and *scanf(). Currently, this reduces the size of libc.so
by 9K on i386. But the real savings are for static binaries that use
*printf() or *scanf() but not strtod(); with an FP-disabled libc,
these binaries will not depend on the gdtoa routines, making each
binary about 22K smaller.
