pooka a17684a24c Add hooks for RUMPRUN build of libc
If "yes", does the following (default "no"):
  * prevents ASM syscalls from being built (librump provides syscalls)
  * does not include compat (useless when application is linked with libc)
  * does not build tags (no /var/db to install them to)
  * does not include tls

==> libc for rumprun can now be built against unmodified NetBSD sources

# All library objects contain sccsid strings by default; they may be
# excluded as a space-saving measure. To produce a library that does
# not contain these strings, delete -DLIBC_SCCS and -DSYSLIBC_SCCS
# from CPPFLAGS below. To remove these strings from just the system call
# stubs, remove just -DSYSLIBC_SCCS from CPPFLAGS.
#
# The NLS (message catalog) functions are always in libc. To choose that
# strerror(), perror(), strsignal(), psignal(), etc. actually call the NLS
# functions, put -DNLS on the CPPFLAGS line below.
#
# The YP functions are always in libc. To choose that getpwent() and friends
# actually call the YP functions, put -DYP on the CPPFLAGS line below.
#
# The Hesiod functions are always in libc. To choose that getpwent() and friends
# actually call the Hesiod functions, put -DHESIOD on the CPPFLAGS line below.
