[PATCH 1/1] busybox: patch to remove -pie from LDFLAGS

[Nimesh Prajapati]

From: Yogesh Prasad <yogesh.prasad at rockwellcollins.com>

Description
This patch will remove '-pie' option from LDFLAGS if it was passed
from TARGET_LDFLAGS. Removing of -pie linker option is required
because it cannot be used with the -r option.
Busybox bydefault enables -r option. if -r and -pie are used together
below error is thrown by the linker.
