[PATCH] backends/ppc_attrs.c: Add PPC long double tags

[A. Wilcox]

When an explicit type of long double is specified in the ELF
GNU_Power_ABI_FP attribute, elflint and friends were erroring out:

    section [36] '.gnu.attributes': offset 15: unrecognized GNU_Power_ABI_FP 
attribute value 9

Add the different long double tags to fp_kinds so that these values
are correctly recognised and printed.
