+Subject: [PATCH 050/160] PowerPC64 pcrel got relocs against local symbols
+
+Not that anyone would want to indirect via the GOT when an address can
+be loaded directly with pla, the following:
+
+ pld 3,x@got@pcrel
+x:
+
+leads to "Internal error in md_apply_fix", because the generic parts
+of assembler fixup handling convert the fx_pcrel fixup to one without
+a symbol.  Stop that happening.
+
+       * config/tc-ppc.c (ppc_force_relocation): Add PLT_PCREL34 and
+       assorted GOT_PCREL34 relocs.
+
+(cherry picked from commit 49c3ed081fed6b8e2b48fdc48f805f11e4589514)
