May I suggest the attached patch instead?
It handles PICFLAG the same way as it was already done
for other architectures (e.g., CRIS and frv).

This should fix the dlsym problem Peter van Hoyweghen reported.
However RTLD_LOCAL still doesn't work. Everything is RTLD_GLOBAL.

PPC32, SPARC32/64 and S390 includes the PLT in its RELA size. This caused ldso
to always do unlazy relocation of the JMPRELs. This patch fixes it.

This patch makes -fpic work for PCC and optimzes the relcation by moving the cache
flushing stuff to JMP relocs only. Actually PPCs ldso can only handle small
GOT tables(<=8192 entries)anyhow, so it makes little sense to compile PPC with -fPIC.
libuClibc shrunk from 340724 to 330780 bytes with -fpic.

Add missing header file needed to define PAGE_SIZE

As Joakim Tjernlund rightly notes, I should have used PAGE_SIZE
not the hard coded value of 4096.

cut-n-paste strikes again

Cleanup some dead wood in the header files

s/___brk_addr/__curbrk/g
Some utilities, such as valgrind, have a legitimate reason to know the address
of the current brk. Since we know such utils will peek under our skirt, we
might as well give them what they expect and not use a gratuitously different
symbol name.

Some mips updates. Add a couple of missing sys/*.h files and update a few others.

Teach libdl to use normal libc symbols whenever possible, i.e. malloc
rather than _dl_malloc, fprintf rather than _dl_printf, etc.
-Erik

Whitespace cleanup

Fix screwed up indenting

Do not grovel about in the ELF header for the page size when
running on uClinux, which at runtime uses the FLAT file format.

Be certain to include sys/sysmacros.h when major() and minor()
are being used

Remove all reference to __GLIBC_HAVE_LONG_LONG

Support linux 2.6.x wide device major/minor numbers

Fix ftruncate64 and truncate64 for powerpc and mips
-Erik

Update todo list

Update sigaction for arm

Add sigaction for mips

Follow glibc's lead and add a gcc-3.4.1 required symbol to crt0.S.

Hide the arm libfloat support for now. No longer needed for gcc 3.4.1 and
won't be needed for 3.3.4 either when I get some time to clean up that
toolchain which also suffers from the g++ include dir search order bug.

Revert this stuff for now

Hi Erik,

I'm not sure why the NIOS support is not in uClibc -- perhaps the patch
was rejected or never submitted? In any case, I'm playing with some NIOS
stuff and created this patch against 0.9.26. The work was done by
Microtronix. I'm not sure who else contributed to it. It would be great
to have the NIOS support available in uClibc so developers don't have to
go searching for these bits.

Cleanup some cruft

update packaging a bit

Cleanup a few of the more egregiously broken sysconf values to
actually match reality. In particular, _SC_GETPW_R_SIZE_MAX and
_SC_GETGR_R_SIZE_MAX were causing us problems with programs such
as libglib, since they were always returning -1, which is a bit
smaller than the actual passwd and group max buffer sizes.
