            Bug ID: 19357
           Summary: ld produces invalid GOT entries for R_386_GOT32X
                    relocations
           Product: binutils

Patch that fixes the problem

Since commit 02a866936de7e63ad4962ccba56c8cd05c231275 ld generates invalid GOT
entries (less than 4 Byte in size) when processing a R_386_GOT32X relocation to
a weak symbol during static linking.  This happens for example when statically
linking a C++ program without using libpthread on Linux.

The attached patch make sure that there is a 4 Byte GOT entry allocated in the
same spacial cases as for the R_386_GOT32 relocation.
