From: Jessica Clarke <jrtc27@jrtc27.com> Date: Thu, 5 Aug 2021 20:25:45 +0100 Subject: Partially revert "build: -no-pie is no functional linker flag" Git-commit: ffd205ef2901bd65fcfbd09a98c0ff7cfcec5e4d References: bsc#1192463 This partially reverts commit bbd2d5a8120771ec59b86a80a1f51884e0a26e53. This commit was misguided and broke using --disable-pie on any distro that enables PIE by default in their compiler driver, including Debian and its derivatives. Whilst -no-pie is not a linker flag, it is a compiler driver flag that ensures -pie is not automatically passed by it to the linker. Without it, all compile_prog checks will fail as any code built with the explicit -fno-pie will fail to link with the implicit default -pie due to trying to use position-dependent relocations. The only bug that needed fixing was LDFLAGS_NOPIE being used as a flag for the linker itself in pc-bios/optionrom/Makefile. Note this does not reinstate exporting LDFLAGS_NOPIE, as it is unused, since the only previous use was the one that should not have existed. I have also updated the comment for the -fno-pie and -no-pie checks to reflect what they're actually needed for.
