When attempting to debug shim in gdb, it currently gives the error: Dwarf Error: DW_FORM_line_strp used without required section

This appears to be the same issue reported here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2014231 (also golang/vscode-go#1914 and haikuports/haikuports#4987), which is nothing to do with shim: current versions of gcc produce DWARF5 by default, but current versions of gdb only accept DWARF4.

Applying the gcc flags suggested in those issues (-gdwarf-4 -gstrict-dwarf) makes shim debuggable again.
