Arch Linux

Description:
Package fails to build from source see attached build.log [1].
Uncommenting CFLAGS+=' -Wno-deprecated-declarations' the build then fails due to -Wmay-be-uninitialized being treated as an error.
Fixing that the build then fails due to the change to -fno-common.
[2] fixes -Wmay-be-uninitialized, [3][4][5] fixes -fno-common [6] fixes -Wformat -Werror=format-security Arch is introducing.
PKGBUILd.diff [7] also stops libtool overlinking.
Links are to mirror repo.or.gz instead of primary repo git.geda-project.org as that uses cgit which includes cgit's version number at end of patches.
