[Boost-build] [boost] patch to correct linker flag sequence

Subject: [Boost-build] [boost] patch to correct linker flag sequence
From: Jay Shah (jay.shah1_at_[hidden])
Date: 2017-11-28 07:21:15

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.

-------------------------------------------------------------------------
/host/powerpc-buildroot-linux-gnu/sysroot/usr/lib/Scrt1.o:(.data+0x4):
 undefined reference to `main'
/host/lib/gcc/powerpc-buildroot-linux-gnu/6.4.0/../../../..
/powerpc-buildroot-linux-gnu/bin/ld: BFD (GNU Binutils) 2.28.1
 assertion fail elf32-ppc.c:8923
collect2: error: ld returned 1 exit status
-------------------------------------------------------------------------
