Subject: [PATCH] build: Make the build flags match Fedora's %{gobuildflags}

The Go toolchain doesn't like the LDFLAGS environment variable as
exported by Fedora's %{meson} RPM macro.

Note that these flags are meant for every CPU architecture other than
PPC64, and should be kept updated to match Fedora's Go guidelines. Use
'rpm --eval "%{gobuildflags}"' to expand the %{gobuildflags} macro.
