From 0eb2fa39f313cac1e1e76c09e6ecf204064697a9 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Fri, 4 Dec 2020 18:32:46 +0200 Subject: [PATCH] rules.mk: use -fPIC instead of -fpic on arm64 Some packages fail to build on arm64 when PKG_ASLR_PIE_ALL=y, due to machine-specific size restrictions on the global offset table. While the manual instructs to recompile with -fPIC if it fails with -fpic, by doing this per package, there is still a risk of random breakage due to version bumps or other changes, so let's use -fPIC on arm64 by default. While comparing the sizes of 141 packages built with -fpic vs -fPIC, most packages are either equal or smaller in size. Only 9 of the compared packages turned out slightly larger.
