I've dug at this for too long.
Xen builds newlib with -nostdinc -isystem SOMEPATH/include

where SOMEPATH=gcc -print-search-dirs | sed -n -e 's/install: \(.*\)/\1/p'

For netbsd's base GCC, that points to a directory with nothing in it.
For pkgsrc GCC, it points to a directory with things like stddef.h in
it.

netbsd doesn't really have a stddef.h anywhere but /usr/include. so I am
not sure what to do.
