scripts/libc: do not build add-ons by default

Currently, no --enable-add-ons option is passed to libc configure when
"$(do_libc_add_ons_list ,)" is empty, which makes configure automatically search
for present add-ons. In that case, all present add-ons are built, although
no add-on was selected by the user in the config. Moreover, this can make the
configure fail if some non-standard add-ons like eglibc-localedef are present.

This behavior also leads to an inconsistency from a user point of view between
the following cases:
- LIBC_ADDONS_LIST="", LIBC_GLIBC_USE_PORTS=n and THREADS="none" in the config,
which makes "$(do_libc_add_ons_list ,)" return "", so all present add-ons
are built.
- LIBC_ADDONS_LIST="", LIBC_GLIBC_USE_PORTS=n and THREADS!="none" in the
config, which makes "$(do_libc_add_ons_list ,)" return the add-on supporting
the chosen threading implementation, e.g. "nptl", so only this add-on is
built.

This patch disables the building of all add-ons in that case.

It is still possible to build all present add-ons by adding --enable-add-ons to
LIBC_GLIBC_EXTRA_CONFIG_ARRAY.

     1 Make psignal prototype in libiberty match that in glibc.

     3 Fixes:

     5 gcc-2.95.3-glibc-2.1.3/binutils-2.15/libiberty/strsignal.c: In function `psignal':

     8 gcc-2.95.3-glibc-2.1.3/binutils-2.15/libiberty/strsignal.c:563: argument `message' doesn't match prototype

    13 make: *** [all-libiberty] Error 2

    15 when building on red hat 7.1

    16 though it's a bit of a mystery why libiberty's psignal is being compiled at

    17 all, since red hat 7.1's glibc supports psignal (hence the error message)
