[BUG?] GCC 4.5.2 produces deprecated ARM relocation

Hi Richard,

Well I based my conclusion upon this note in gas/doc/c-arm.texi:

    For compatibility with older toolchains the assembler
    also accepts @code{(PLT)} after branch targets.  This
    will generate the deprecated @samp{R_ARM_PLT32} relocation.

I do not mind enhancing the assembler however, so what do you think of 
the attached patch ?

Cheers
