[pseudo][PATCH] configure: Prune PIE flags

[pseudo][PATCH] configure: Prune PIE flags

[Khem Raj]

LDFLAGS are not taken from environment and CFLAGS is used for LDFLAGS
however when using security options -fpie and -pie options are coming
as part of ARCH_FLAGS and they get into LDFLAGS of shared objects as
well so we end up with conflicting options -shared -pie, which gold
rejects outright and bfd linker lets the one appearning last in cmdline
take effect. This create quite a unpleasant situation in OE when
security flags are enabled and gold or not-gold options are used
it errors out but errors are not same.

Anyway, with this patch we filter pie options from ARCH_FLAGS
ouright and take control of generating PIC objects

Helps with errors like
