We can't strip libpthread or libthread_db can't help gdb debug ptheads

That last patch had some garbage in it... PIC != PIE

Partial commit of a patch from Alexandre Oliva:

Here's an updated version of the patch I posted about a month ago. It
leaves -nostdinc alone, and uses -print-file-name=include instead of
-print-search-dirs to figure out where GCC's internal headers are.

Please let me know whether there are any portions of this patch you'd
like me to break into smaller pieces, to rework, or to give up trying
to get into uClibc :-) Thanks,

Remove some accumulated ugly junk

Don't use PAGE_SIZE, instead just a local BUFFER_SIZE define

libpthread can use the normal LDFLAGS (including -s to strip it), but
libthreaddb must not be stripped or gdb can't use it.

Kill off ancient unused cruft

Use PAGE_SIZE, not 4096

Add missing definition for O_DIRECT

update : $

Make __builtin_return_address() return NULL at top of
stack frame. This will make backtracing possible.

Add BIND NOW support to MIPS.

Mips did not honour the LD_BIND_NOW env. variable or the DT_BIND_NOW flag
in the dynamic section.

Fix grammar

move getent to extra/scripts/ out of docs/

misc touchups

fix a few typos and clean up the spacing (no tabs)

misc cleanups of __stack_smash_handler() function when ssp support is enabled. syslog() support should now work both inside and outside of chroots. erandom code left in but remains #ifdef out by default. May remove erandom completely in the future for uClibc unless the LFS guys and gals want to keep it.

Add RTLD_LOCAL support for dlopened libs. Reported by
Andrew de Quincey, who has been most helpful getting this sorted
out, thanks. Thanks also to Peter Mazinger who did alot of testing.

Removed all traces of dl_parse_copy_information() since it is no longer used.

initial commit of uclibc equiv of glibc getent

Some requested additional malloc entry points

A patch included in glibc 2.3.2's libthread_db that helps remote
debugging not become confused,

struct ipc_perm, as used by shmctl() when soing shared memory stuff,
was incorrect in uClibc, and was 2 bytes too short. This caused uClibc
shared memory stuff to not behave correctly since struct ipc_perm was
included as the first member of, i.e. struct msqid_ds, so the content
of that struct were all shifted by two bytes. ugh. Apparently, few
people have used shared memory, msgctl(), etc with uClibc thus far,

- Remove dynamic_size from struct elf_resolve.
- Replace all open coded dynamic handling with a function. Reduces size.
- Fold special MIPS dynamic code into the dynamic_info item.
- Add RELRO support.
- Support linking with "-z now".
- prepare for DT_RELACOUNT/DT_RELCOUNT optimization.
- Add -z now to ld.so linking, this is what ld.so does anyway so
let the linker know that.

Revert Peter's __lib_gettimeofday patch. There's the minor issue of
adding cruft to include/sys/time.h. But also, there's no sense in
making changes like this until we decide how we're going to approach
the hidden symbol transition.

Synchronized with glibc (2.3.2).

Do not assume a fifth argument is used with syscall(). Allocate stack
for saving SRP separately.

Revise TODO list for the upcoming release

Jocke's patch was almost right. Just needed move the DT_MIPS_RLD_MAP test
up a bit. Native and remote debugging of shared libs and threaded apps now
works on mips.

Fix up __uClibc_init() for so that we prevent starting SUID
binaries where the standard file descriptors are not opened.
