[PATCH] fix missing ifdefs in syscall classes hookup for generic targets

[PATCH] fix missing ifdefs in syscall classes hookup for generic targets

[Al Viro]

several targets have no ....at() family and m32r calls its only chown variant
chown32(), with __NR_chown being undefined.  creat(2) is also absent in some
targets.
