+Subject: [PATCH 1/1] ncurses: patch to correct linker flag sequence
+
+Description
+ This patch will correct the sequence of -pie and -shared options.
+ When used together, -pie should be provided to the linker before
+ -shared. If -pie is provided after -shared, the linker throws an
+ error shown below as example.
+
+The patch fixes Makefile.am for below libs within setools:
+ - libncurses.so.6.0

+/host/powerpc-buildroot-linux-gnu/sysroot/usr/lib/Scrt1.o:(.data+0x4):
