buildsys: fix pregen target (!NPTL with LOCALE)

When NPTL is not enabled, and LOCALE support is used, compilation fails
with the following error:

-------------------------------------------------------------------------
MKDIR include/bits
GEN include/bits/sysnum.h
make[1]: *** No rule to make target `../..//include/bits/uClibc_ctype.h', needed by `../../extra/locale/gen_wc8bit.c'. Stop.
make: *** [pregen] Error 2
-------------------------------------------------------------------------

The problem is that "headers" is not listed as prerequisite of pregen.
These have been changed multiple times recently:

o Austin: order headers before pregen-headers
1f5c73c9f8a98b1d2a35cea868a585c97ab0e436
o Khem: pregen: Fix the parallel build problem in pregen target

o Khem: pregen-headers: Add new target which depends on headers.

o Carmelo: build: Fix infinite loop when no threading support is enabled
ff5e4de7088fe8d34812c2a1e604bf04be713606
In all of these commits headers was actually as prerequisite

In commit 9381d622e2411a35a5fd73a5a573eb269e2dd9c9 [nptl: fix buildsys] by Bernhard, headers was removed,
causing the problem reported above.

Correct a bug when remapping textrel segments on nommu

From: Alan Davis <adavis@ti.com>

On C6X, when trying to execute a program that has a textrel DSO, it
fails to load. The telltale line in the LD_DEBUG output is:

_dl_get_ready_to_run:779: file=''; needed by './a.out'

The corresponding DT_NEEDED entry has 'libc.so.0', but here the
filename is empty. This is what is happening in
_dl_elf_shared_library():

First, map all segments according to their permissions. Text gets
initially mapped read-only.

Then, parse the dynamic information. The dynamic table is in RW but
some of the tags may point to RO. For example, DT_NEEDED points to a
string in .dynstr which is in RO. These pointers get computed
according to the loadmap from the original mapping.

Then, in response to a DT_TEXTREL tag, the RO segment gets remapped,
thereby invaliding anything that points to it, in particular certain
dynamic tags such as DT_NEEDED.

The following patch re-parses the dynamic info after the remapping so
as to re-compute any invalid pointers.
