You would need at least the following:

* Tools, such as make, a compiler, assembler, linker, objcopy, 
sed, awk, sort, and several more.  You probably don't need yacc or 
lex.

* Include files, as installed by "make install" in the NetBSD src 
tree.  Not all of them are used in the libc build, but there is no 
central list of what's needed by libc versus what's needed by some 
other part of NetBSD.

* Source files used in the libc build, especially src/lib/libc/** 
and src/common/lib/libc/**, plus a few things from src/external/** 
and src/sys/external/** which can be identified by searching for 
"external" in all the makefiles under src/lib/libc, and perhaps 
more that I missed.
