Subject: [PATCH] build: Make the build flags match RHEL's %{gobuild} for PPC64
517389
517389
The Go toolchain doesn't play well with passing compiler and linker
517389
flags via environment variables. The linker flags require a second
517389
level of quoting, which leaves the build system without a quote level
517389
to assign the flags to an environment variable like GOFLAGS.
517389
517389
This is one reason why RHEL doesn't have a RPM macro with only the
517389
flags. The %{gobuild} RPM macro includes the entire 'go build ...'
517389
invocation.
517389
517389
The Go toolchain also doesn't like the LDFLAGS environment variable as
517389
exported by RHEL's %{meson} RPM macro, and RHEL's RPM toolchain doesn't
517389
like the compressed DWARF data generated by the Go toolchain.
517389
517389
Note that these flags are only meant for the "ppc64" CPU architecture,
517389
and should be kept updated to match RHEL's Go guidelines. Use
517389
'rpm --eval "%{gobuild}"' to expand the %{gobuild} macro.
