# The default `go build` process embeds debugging information. Building

# We also include additional flags in an effort to generate static binaries

# be a mixed bag, so YMMV.

# See https://github.com/golang/go/issues/26492 for more information.

#	Omit the symbol table and debug information.

#
# -trimpath

#   NOTE: Using external linker requires installation of `gcc-multilib`

#   seems to result in an unstable build that crashes on startup. This *might*
