[pacman-dev] [PATCH] libmakepkg: fix detection of file names with future gcc versions

[Allan McRae]

The current gcc build from git master give different output from
readelf:

gcc-10.2.0
$ readelf "hello" --debug-dump | grep hello
<11> DW_AT_name : (indirect string, offset: 0xbfc): hello.cpp

gcc-git
$ readelf "hello" --debug-dump | grep hello
<12> DW_AT_name : (indirect line string, offset: 0x0): hello.cpp

This causes the awk statement extracting the file name to fail as it
relied on the information being in the 8th field. Instead, extract
the information from the final field.

Fixes FS#70168
