[hurd, commited] powerpc longjmp: Fix build after chk hidden builtin fix

[Samuel Thibault]

04bf7d2d8a79 ("chk: Add and fix hidden builtin definitions for *_chk")
added an #undef for longjmp and siglongjmp to compensate for the
definition in include/setjmp.h, but missed doing so for the powerpc
version too.
