Subject: gcc: move the optimized assembler helpers back into the static libgcc and skip relink... 
X-Git-Url: https://git.rohieb.name/openwrt.git/commitdiff_plain/0e2d55e3e345e55a4c9c7335d42501301834d732?hp=be4aa36f4873365cbb465e3dfc648d023b681853

gcc: move the optimized assembler helpers back into the static libgcc and skip relinking for this arch. due to relocation constraints, the assembler functions cannot be in the shared libgcc and must always be linked in statically
