NetBSD comes with binutils 2.16.1 and some fixes so switching to
2.18.50 solves this thumb issues. The whole tree does not compile with
ld and others from binutils-2.18.50 but enough to run thumb mode /bin/sh 
and /bin/cat work with thumb mode /lib/libc.so and others. Though
/libexec/ld.elf_so still needs to be in ARM mode.

Thank you, Richard!
