From da3700988d9e34e380bae21ee23d5458a7e972b4 Mon Sep 17 00:00:00 2001 From: Andre Heider Date: Thu, 2 Feb 2023 21:16:21 +0100 Subject: treewide: add support for "gc-sections" in PKG_BUILD_FLAGS This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-gc-sections". Note: libnl, mbedtls and opkg only used the CFLAGS part without the LDFLAGS counterpart. That doesn't help at all if the goal is to produce smaller binaries. I consider that an accident, and this fixes it. Note: there are also packages using only the LDFLAGS part. I didn't touch those, as gc might have been disabled via CFLAGS intentionally.
