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.

older verisons of glibc would build dl-sysdep as shared-only and dl-support as

2 |
static-only. alpha hooks in a cache variable via dl-auxv.h. newer versions of

|

glibc build dl-sysdep as both shared and static which means we now have symbol
|
yann@2437
|
4 |
duplication for static builds with dl-sysdep and dl-support. since dl-sysdep
|
yann@2437
|
5 |
is both shared/static, there is no point in hooking dl-support anymore, so we

|

can punt it.
