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.

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.

bugs in gentoo's QA.
Just add UCLIBC_HAS_SSP to the "and" of link.asneeded to properly take SSP
into account, if you prefer.

- 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.

libc when one of the source files changes.
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.

to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place.

possible. Add clean targets for linuxthreads[_db].

archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally.

objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

defer only for shared lib related stuff, because it is optional. Run STRIPTOOL only once. More use of /$^/$<.

ln.patch:
* Define $(LN) as ln in Rules.mak.
* Change all occurrences of ln into $(LN).
* Change all constructs like (cd path && ln -sf foo/file file)
into $(LN) -sf foo/file path/file. The latter construct is
already used in a number of places so it should not be
an additional compatibility problem.
|
|
rm.patch:
* Define $(RM) as rm -f in Rules.mak and test/Rules.mak
(this is the same definition as gmake uses by default).
* Change all occurrences of rm and rm -f into $(RM).
|
|
install.patch:
* Define $(INSTALL) as install in Rules.mak.
* Change all occurrences of install into $(INSTALL).
* Change all occurrences of mkdir -p into $(INSTALL) -d.
install -d is already used in a number of places so
this should not be an additional compatibility problem.

(i.e. openssh) do the right thing when used with uClibc's gcc
wrapper (which does not currently prevent system libraries from
leaking into the link).
