If pkg-config is used in a multiarch or cross-compiling scenario it's likely pkg-config needs to behave differently for each of them. It's possible to handle this through environment variables with one pkg-config, but another option is to have one pkg-config per platform, each with the host alias prefixed to the program. PKG_PROG_PKG_CONFIG supports this type of installation, and this is also how autoconf/libtool handle other build tools like compilers and linkers. The host-prefixed tool is installed as a hardlink where supported and a copy otherwise. This is how gcc handles it's host-prefixed versions. This feature can be turned off by passing --disable-host-tool to configure. Freedesktop #130
