David Schultz 757edc654e 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.

# All library objects contain FreeBSD revision strings by default; they may be
# excluded as a space-saving measure. To produce a library that does
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
# below. Note: there are no IDs for syscall stubs whose sources are generated.
# To include legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
# to CFLAGS below. -DSYSLIBC_SCCS affects just the system call stubs.
