Package: dpkg-dev Version: 1.20.5 /usr/share/dpkg/architecture.mk is very slow:
$ time printf 'include /usr/share/dpkg/architecture.mk\nall:\n\ttrue\n' | make -f - > /dev/null real 0m1.161s user 0m1.009s sys 0m0.127s strace tells me this is because it spawns dpkg-architecture 33(!) times. Please speed this up. -- System Information: Architecture: i386 Versions of packages dpkg-dev depends on: ii perl 5.30.3-4 ii libdpkg-perl 1.20.5 ii tar 1.30+dfsg-7 ii bzip2 1.0.8-4 ii xz-utils 5.2.4-1+b1 ii patch 2.7.6-6 ii make 4.3-4 ii binutils 2.35-2 -- Jakub Wilk
