+Subject: [PATCH] Generate position independant code for static library
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+Currently, only shared libraries are using the PIC flag.
+
+Generalize this flag for static libraries in order to let them linkable
+by dynamic libraries.
+
+Fixes:
+
+	/home/gportay/src/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-amd-linux-gnu/6.2.0/../../../../x86_64-amd-linux-gnu/bin/ld: /home/gportay/src/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libmemenv.a(memenv.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
+	/home/gportay/src/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libmemenv.a: error adding symbols: Bad value

+Upstream-Status: Inappropriate [upstream has migrated to cmake]
