Don't use -g3 when compiling grub2 none

Description Sergio Durigan Junior 2019-05-10 20:32:58 UTC 
Hi,

There is an existing bug (probably on rpm-build's debugedit) which introduces a problem on .debug_macro sections in objfiles and causes GDB to segfault when trying to extract the DWARF index (via the gdb-add-index script).

This bug manifests when a binary is built using GCC's -g3 flag, which is the case with grub2.  The workaround for it is to just build it with -g, which is also the recommended flag for building Fedora packages.

I will provide a patch that does that.

Related: Bug 1708192 and Bug 1535174.

Thanks.

Thanks a lot for the patch. I've picked it and built grub2-2.02-88.fc31 that includes this.

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to 31.
