pkg-config-arm-linux-gnueabihf 4:7.3.0-2ubuntu1 (amd64 binary) in ubuntu bionic

 pkg-config is a system for managing library compile and link flags that
 works with automake and autoconf.
 .
 Increasingly libraries ship with ".pc" files that allow querying of the
 compiler and linker flags needed to use them through the pkg-config(1)
 program.
 .
 This is a dependency package providing cross pkg-config support for the
 armhf architecture.
