Print build environment info when using eln target

[matsl]

What

Matsl rsw echo emacs and env info

Why

We need to show emacs version when compiling natively to make it easier to see that the proper version is used.

Note

Reuses the echo target for printing the environment and added emacs version info to echo target as well.

Thanks, Mats.  That works but can you tell me how to override the EMACS var value on the command line.  Adding ‘EMACS=path’ either befor or after ‘make eln’ did not work for me.  -- BobOn Jan 16, 2024, at 10:24 AM, Mats Lidell ***@***.***> wrote: Merged #445 into rsw. —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because your review was requested.Message ID: ***@***.***>

Ah. You want to be able to control which Emacs is used not only get a confirmation which is!? In that case we need to do it differently. New PR will come.

We did already have a makefile MACRO that can be used to control which Emacs is used. This PR #446 updates the echo target to use the MACRO so that echo reports about the version that is used. So make EMACS= ... should work.
