[Skiboot] [PATCH 2/7] external/pflash: Fixup LDFLAGS

[Cyril Bur]

In order to be able to compile for something that isn't the default for the
compiler one should be able to use CFLAGS and LDFLAGS on commandline.
ie build a 64bit binary with a compiler which builds by default 32bit or
the opposite endian for which the compiler is configured.

Currently the common/rules.mk ignores LDFLAGS when it shouldn't and pflash
sets LDFLAGS for something which only applies to the final link.

This patch addresses both those issues.
