This reverts the below commit to not generate PLT32 relocs
on branches by default.  Used for old distros to not have to
update several packages/tools that can't handle them.  I.e.
a compatibility patch.

The changes in nop-[345].d and pr22842b.S are followups to
not break the testsuite because of this revert.

x86-64: Generate branch with PLT32 relocation
    
    Since there is no need to prepare for PLT branch on x86-64, generate
    R_X86_64_PLT32, instead of R_X86_64_PC32, if possible, which can be
    used as a marker for 32-bit PC-relative branches.
    
    To compile Linux kernel, this patch:
    
    From: "H.J. Lu" <hjl.tools@gmail.com>
    Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32
    
    On i386, there are 2 types of PLTs, PIC and non-PIC.  PIE and shared
    objects must use PIC PLT.  To use PIC PLT, you need to load
    _GLOBAL_OFFSET_TABLE_ into EBX first.  There is no need for that on
    x86-64 since x86-64 uses PC-relative PLT.
    
    On x86-64, for 32-bit PC-relative branches, we can generate PLT32
    relocation, instead of PC32 relocation, which can also be used as
    a marker for 32-bit PC-relative branches.  Linker can always reduce
    PLT32 relocation to PC32 if function is defined locally.   Local
    functions should use PC32 relocation.  As far as Linux kernel is
    concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32
    since Linux kernel doesn't use PLT.
