upgpkg: pacman 6.0.1-4: backport support for LTOFLAGS
Set LTOFLAGS="-flto=auto" in the shipped makepkg.conf. This release
also drops the "-fvar-tracking-assignments" flag from makepkg.conf.
Also include the following two commits (related to debugflags / lto):
- makepkg: use -ffile-prefix-map instead of -fdebug-prefix-map
- libmakepkg: add extra buildflags only when buildflags is not disabled
Added:
pacman/trunk/libmakepkg-add-extra-buildflags-only-when-buildflags.patch
pacman/trunk/make-link-time-optimization-flags-configurable.patch
pacman/trunk/makepkg-use-ffile-prefix-map-instead-of-fdebug-prefi.patch

+Subject: [PATCH] Make link time optimization flags configurable
+
+We want to use -flto=auto in Arch Linux to speed up building, but we
+can't hardcode it in buildenv/lto.sh because other downstreams might
+have clang < 13.0.0 which did not recognize -flto=auto as equivalent
+to -flto=full.
+
+Introducing an LTOFLAGS variable to makepkg.conf seems the way to go.

+>From gcc(1):
+
+-ffile-prefix-map=old=new
+ [...] Specifying this option is equivalent to specifying all the
+ individual -f*-prefix-map options. This can be used to make reproducible
+ builds that are location independent.
+
+Specifically, this additionally enables -fmacro-prefix-map=, which causes
+prefix mapping to be applied to expansions of __FILE__ and similar macros.
+
+Without this option, if source files are compiled by passing the
+absolute file path to the compiler (as done by e.g. cmake), any
+expansions of __FILE__ (e.g. from uses of assert()) will contain
+$srcdir.
