libc symbols are missing

[kazzmir]

The following symbols seem to be missing from PSL1GHT. host/ppu/ppu/lib seems like the most likely place they would be, namely libc.a.

access
dup2
getpwuid
getgrgid
seteuid
getuid
geteuid
setegid
getgid
getegid
getgrnam
setgid
getpwnam
setuid
getlogin

I don't really care if the set/get uid stuff are no-ops, but I need access() and dup2().
