nostdlib disables linking in startup files too which is not
what we want here since it needs to resolve __dso_handle
which comes from crtbeginS.o, otherwise librt has this
undefined reference to a weak undefined __dso_handle that
shows up as error (with gold linker)
when shared libraries are being built which are
linking in librt

Not all architectures use 'ret' as function return instruction. For example,
xtensa usually uses 'retw'. Use the ret_ERRVAL arch dependant macro instead.

If ADVANCED_REALTIME is disabled, these prototypes are missing and
librt_hidden_proto() fails.
Makefile.in: added a comment, we build mq_timedreceive/mq_timedsend
on NPTL even if ADVANCED_REALTIME is disabled.

Should make adding more knob control simpler as people only need
to modify one variable now (librt_filter_SRC).

Avoids warning from -Wunused-function about the alias target that is

This adds support for a new binary format, DSBT ELF, to the Makefiles.
Every shared library is assigned a DSBT index, and the link.so macro is
adjusted to ensure the correct linker argument is passed.
Configuration and ldso support will follow in separate commits.

Linking order matters. Always did and still does today.
See how this makes the ugly and wrong hack to put pthread symbols into
librt _and_ linking librt against pthread moot?

Since sublevel releases are not ABI compatible we need to adjust
the soname to include the sublevel version.
This makes it possible to install ABI incompatible versions of the
library side by side so clean upgrades are possible.

In any non-buggy program free() does not fail.
And when it fails in a buggy program, the failure
is usually fatal (heap corruption and segfault).

- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few
This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.

Since there are more places which want to depend on $(libc), fix them all to
use a new variable $(libc.depend), which contains the filename for which we
have a rule.
