hppa: Fix setting of __libc_stack_end
The binutils package was recently changed to fix -z relro support on hppa.
See ld/21000 for details:
https://sourceware.org/bugzilla/show_bug.cgi?id=21000
This exposed a problem with the _dl_start_user function in the RTLD_START
define. We need to set __libc_stack_end before it is made read only. For
this, we need to define DL_STACK_END. The offset of 0x160 gives the same
stack end as the code in _dl_start_user.
A build log with the attached patch is here:
