Hi Solra,

I have build rules that I use to build compiler-rt and libc++ for 
various targets
including big and little endian ARM hard and soft float.
You can find them at http://ellcc.org/viewvc/svn/ellcc/trunk/libecc/
Makefile is the Main build file. It creates a target specific directory 
and copies
Makefile.lib into it. Makefile.lib is then used to build the actual library.
You'll need to tweak the build rules a bit since I rely on ELLCC's use 
of config files
to define where include files are and what compiler options to use.
The config file for armeb: 
http://ellcc.org/viewvc/svn/ellcc/trunk/libecc/config/armeb-linux-engeabi?view=markup

Hope this helps.
