+Subject: [pseudo][PATCH] configure: Prune PIE flags
+
+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
