[Buildroot] crosstool-ng and uClibc toolchain

Hi,
I have been looking at building a toolchain using 2011.11 building it
with crosstools-ng and uClibc.
It currently seems a little bit broken/limited. I can supply a custom
ct-ng config, which specifies 0.9.32 but I am unable to select NPTL
threading or to specify a custom uClibc config file.
Also if I choose to use libthreads.new then the build fails as the
config file passed to build libc headers has no threading option
enabled. This problem is I think caused by the uClibc config file you
have to use. It contains LINUXTHREADS_OLD=y but there is not a not set
entry for LINUXTHREADS_NEW which means the sed command to set it can't work.
In fact the uClibc config you are forced to use has lots of settings I
would consider wrong.
Am I correct thinking these things are broken or am I missing something?
Am currently working on a patch that does the following:
- Allow user to pick uClibc version when using ct-ng
- Allow user to select nptl when using 0.9.32
- Supply better default uClibc config files (Using same config files as
for internal buildroot config)
- Allow user to specify a custom uClibc config file
Assuming I can get it working I'll post it.
Thanks
Will
