[uClibc] ARM shared libs segfault

[David Poole]

I seem to have a working ARM uClibc toolset with binutils 2.15. The  
previously posted patches with a few other tweaks got me up and  
running. The loader still segfaults (see below).

The recent tweaks:

- make/libfloat.mk wants to install libfloat into /usr/lib and /lib  
which is annoying and unnecessary.
- another difficulty with make/libfloat.mk; the linker can't find  
libfloat when linking libuClibc-0.9.26.so so the compile will fail. I  
copy libfloat to the arm-linux-uclibc-ld's SEARCH_DIR (reported by  
"/home/davep/src/toolchain/gcc-3.3.x/toolchain_arm_nofpu/bin/arm-linux- 
uclibc-ld  -V --verbose").

- Once the toolchain is built, something is installing uClibc library 
links incorrectly.
./toolchain/gcc-3.3.x/toolchain_arm_nofpu/arm-linux-uclibc/lib contains 
library links to ../../../../arm_nofpu/arm-linux-uclibc/lib which 
doesn't exist. I created a link: ./toolchain/arm_nofpu -> 
./toolchain/gcc-3.3.x/toolchain_arm_nofpu/ to work around the problem.

For completeness, here are the other two patches:

The bad news is upgrading uClibc to binutils-2.15 didn't fix the 
problem. The loader still segfaults when linked with ld 2.15. But now I 
know it's a problem in the linker itself and not a patch from uclibc's 
toolchain script.

The fun continues.
