The "linuxbase" has __errno_location as part of the binary spec; as 
it's not part of POSIX or the Unixbase specs, we haven't added it yet, 
although me might do, at least as a temporary measure.
Anyway, adding the following line to src/kernel/libroot/posix/errno.c 
should fix your problem:
extern int *(*__errno_location)(void) __attribute__ ((weak, 
alias("_errnop")));

And a question for everybody: should we add this temporary or even 
permanently to errno.c?
We could probably have it only compiled in when building under linux 
for now, though.

Yes.
