Subject: [PATCH] build: Make the build flags match RHEL's %{gobuildflags} for
 PPC64

The Go toolchain also doesn't like the LDFLAGS environment variable as
exported by RHEL's %{meson} RPM macro, and RHEL's RPM toolchain doesn't
like the compressed DWARF data generated by the Go toolchain.

Note that these flags are only meant for the "ppc64" CPU architecture,
and should be kept updated to match RHEL's Go guidelines. Use
'rpm --eval "%{gobuildflags}"' to expand the %{gobuildflags} macro.
