I see you are using external (precompiled) toolchain, right? I don't know 
if that might be the case for missing header locations...

The compilation lines that fail are the same in my and your case, 
but you are using libc based instead of uclibc based compiler and 
I suspect that my compiler looks for headers in STAGING_DIR/usr/include
without the -I switch added. 

Can we see the output of failed compile with '-v' option added?

Here is mine:

It can be seen that my compiler looks in '/tmp/buildroot/build_arm/staging_dir/usr/include' for headers, 
where termcap.h is located - does compiler search there too?

Fine, the header seems to be in place. But does the compiler know where to look?
