Subject: build: add support to use the mold linker for packages
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fhauke.git;a=commitdiff_plain;h=32ed9764462ae04fad5809f857450d4f606ac4c0

build: add support to use the mold linker for packages

If CONFIG_USE_MOLD is set, all target packages will use the mold linker.
Except the ones which opted-out via setting PKG_BUILD_FLAGS:=no-mold.
