[bug#42882] [PATCH] system: Modify GDB skeleton to find debug files for any profile.

Hello Maxim,

You could say the "optional Guile integration", because it is (sadly)
disabled on Ubuntu's gdb build for instance.

And maybe precise that this very snippet will be installed by default as
.gdbinit on Guix System?

Otherwise it looks fine to me.

Thanks,
