[Bug-readline] [PATCH 1/1] readline: patch to correct linker flag sequence

[Nimesh Prajapati]

From: Yogesh Prasad <address@hidden>

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:
 - libhistory.so.7.0
 - libreadline.so.7.0
