# Remove certain flags from $LDFLAGS to fix validation errors in
# Go >= 1.15.5 like:
# go build runtime/cgo: invalid flag in go:cgo_ldflag: -Wl,-O1
filter-ldflags "-Wl,-O1"
#
# Note, we need to manually strip only the optimization element of
# comma-separated flags, e.g. from `-Wl,-O1,-s` to `-Wl,-s`.
# To support multiple characters that can follow `-O`, e.g. `-Ofast`,
# we should use regexp like `[[:alnum:]]*`.
# Work-around for https://github.com/golang/go/pull/42631.
