I added uclibc_nonshared.a support uClibc. This involved creating a linker 
script libc.so with the following line:
GROUP ( path_to/libc.so.0 path_to/uclibc_nonshared.a )

At build time (running make) in TOPDIR/libc I create this by having 
path_to as $(TOPDIR)lib. In install_dev I rewrite this line to
GROUP ( RUNTIME_PREFIX/libc.so.0 DEVEL_PREFIX/lib/uclibc_nonshared.a )

A possible failure is, that libc.so is created before libc.so.0 is already 
installed.

To hopefully correct this issue:
I have splitted out the header installation from install_dev into 
install_headers (install_dev installs the library links and depends on 
install_headers, so it should behave as earlier).
I have also added an additional condition for the creation of libc.so, 
checking if the RUNTIME_PREFIX/lib/libc.so.0 file is already installed, so 
libc.so shouldn't be installed if it is useless.

To really behave correctly, after buildroot is corrected I am intending 
to add install_dev dependency on install_runtime and install_headers 
dependency on headers, then all the additionally added checks can be 
removed.

Please test current svn in buildroot and see if it works for you now.

Thanks, Peter
