lvm2: fixed detection of malloc() and realloc() when cross-compiling
musl: fixed to always install libc headers

This changes the behavior which was to install headers only at stage 0,
which was sufficient to build a proper toolchain and to cross-compile,
but as the headers have not been installed at stage 1 we have not header
files within the flist of the musl package.
Now we are always calling the 'install-headers' target when calling make
install, but we need to 'touch' every header file within the sources to
be able to install the headers even if already existing in the build
sandbox.
linux: Updated (3.10.9 -> 3.10.10)
linux-src: Updated (3.10.9 -> 3.10.10)
linux-header: Updated (3.10.9 -> 3.10.10)
csprng: enable cross-compiling at stage 1 if requested by the target
pgbouncer: added patch to not include <sys/poll.h>

The reason for removing <sys/poll.h> from getting included is that musl
explicitely tells to correct the code when <sys/poll.h> is included,
changing it to include <poll.h> only as the standard documents suggest!

argp-standalone: Added argp-standalone 1.3 - An interface for parsing unix-style argument vectors
csprng: fix cross-compiling against other libc implementations than glibc

Note:

This change assumes that the libc used implements a "gnu compatible" malloc.
argp-standalone: fixed compiling by re-adding a patch from jsaw

This patch was within our repositoy yet, but was part of rng-tools, because
an historical version of the rng-tools had argp-standalone bundled within.
csprng: improved to be able to disable the fetching of random data via http
csprng: disable http rng feature at stage 1 because it is implemented in C++
csprng: fixed to build if the libc is not including an internal argp implementation
csprng: renamed patch for disabling http rng
csprng: add portability fixes
csprng: fixed patch that adds --disable-http-rng option

variables shouldn't be "prefixed" with a \t.
ca-certificates: Updated (1.83 -> 1.87)
csprng: improved patch dealing with error.h portability
musl: improved parse-config-9 to inject common config cache variables
haveged: changed to build at cross stage if requested
