kbuild: add package-dbg to pacman packages

[PATCH] kbuild: add package-dbg to pacman packages

Posted by 1127955419@qq.com 2 months ago

From: Li XingYang <1127955419@qq.com>

The current pacman package does not include the debuginfo package
add debuginfo package that include vmlinux
vmlinux is very useful when debugging the kernel using crash

This is already implemented in
"kbuild: add debug package to pacman PKGBUILD"
which is in the kbuild tree.

https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git/commit/?h=kbuild&id=4929f5b95f6b20ae10f2c409fb2ca58253e73706
