Command you pasted is truncated and it is hard to tell what is going on 
here.
Send me full log for incremental build and i'll check if i have any 
further ideas.

BTW, is libawt.so present in your build tree?
You may also try to run make from make/java/awt but i am not sure if it 
will help.

I believe mapfiles are used to defines set of methods to be exported 
from shared library.
Perhaps, you may grep build log file for mapfile name to see how this is 
done exactly
(do not have linux build here and have not checked log myself).

My understanding of why we use this is following.
Symbol tables for all methods from the library are large and explicit 
control on set of exported methods
is workaround to reduce library file size (and size has impact on memory 
footprint, download footprint, startup time, etc.).
