I don't think you need to add those manually:

packages/lang/golang/golang-version.mk

Lines 232 to 244 in 6c11904

	PKG_GO_LDFLAGS?= \
	-buildid '$(SOURCE_DATE_EPOCH)' \
	-linkmode external \
	-extldflags '$(patsubst -z%,-Wl$(comma)-z$(comma)%,$(TARGET_LDFLAGS))' \
	$(if $(CONFIG_NO_STRIP)$(CONFIG_DEBUG),,-s -w)
	PKG_GO_INSTALL_ARGS?= \
	-buildvcs=false \
	-trimpath \
	-ldflags "all=$(PKG_GO_LDFLAGS)" \
	$(if $(PKG_GO_GCFLAGS),-gcflags "all=$(PKG_GO_GCFLAGS)") \
	$(if $(PKG_GO_ASMFLAGS),-asmflags "all=$(PKG_GO_ASMFLAGS)") \
	$(if $(filter $(GO_PKG_ENABLE_PIE),1),-buildmode pie)

NetBird is huge indeed so any shrinking can be helpful
Have you checked that this actually works as I think some optimisations like -s -w are already standard.
We might need the help of the golang expert @GeorgeSapkin

[GeorgeSapkin]

This is roughly the same as stripping.

[GeorgeSapkin]

This is set already in the default vars. Is this package not using them?

[GeorgeSapkin]

The toolchain already strips binaries by default. Is this somehow not the case for Netbird?

[wehagy]

Like @GeorgeSapkin and @LGA1150 mentioned, this option is already the default and netbird doesn't change any of these options.

@ShayBox, can you build a package and an image with and without your patch and show the difference?
