[Bug binutils/11549] New: Allow 32bit relocations in 64bit code

[dev at sw dot ru]

Unfortunately, elf64_x86_64_check_relocs prohibits 32bit relocations, which 
makes it impossible to link 32/64 bit code together in some cases though may be 
needed in low-level loaders and such.

We faced this problem when tried to link together 32bit asm code with 64bit 
system code. The target binary is loaded at virtual addresses lower then 4GB, 
so 
there is no problem in such a mix, except for ld doesn't allow to link the code 
together.

Attached patch fixes the problem.
