Subject: [PATCH] build: LDFLAGS pass -pie flag explicitly to ld
When building with some toolchains, the gcc -pie option does not
enable the linker pie without explicitly passing it to ld,
resulting in a non-PIE binary that silently fails (due to
relocation failure). This was observed with the powerpc64le
cross compiler for Debian.
Pass -Wl,-pie explicitly, which allows the powerpc64le toolchain
to create a position independnet binary that boots.
