PR21132, hppa-linux pie support doesn't work

Browse Source 
This fixes a long-standing hppa bug seen when generating PIEs, and I
think possible to trigger with forced local symbols in shared
libraries.  Not allocating enough space for PLT relocs results in ld
writing outside of the buffer.

	PR 21132
	* elf32-hppa.c (allocate_plt_static): Allocate space for relocs
	if pic.
