This error doesn't come from emacsclient, it comes from the async
native compilation.  Did you upgrade your system lately, in particular
GCC and/or Binutils?

See? it's ld, the linker, complaining that it cannot find a library
(libgcc) it needs for producing the .eln file.

You should verify your libgccjit installation is working correctly.
Which GCC version do you have?

FWIW, I have no problems building the current emacs-29 branch with
native-compilation.  I just tried.

This is not the latest emacs-29 branch, btw (not that I expect a
slightly outdated revision of the branch to fail to compile).
