The script contains the following:
"""
# using our installed *.pc only - neither default nor user paths
export PKG_CONFIG_LIBDIR="${prefix}/lib/x86_64-linux-gnu/pkgconfig"
"""
pkg-config's manpage says:
"""
[...]
PKG_CONFIG_LIBDIR
Replaces the default pkg-config search directory.
[...]
"""
To be honest, I cannot figure out if it is a special case that happens
to work or it is subtly still broken.
It happens to work only if architectures of libsane-dev and libsane-bin
match. If they don't, it's non-subtly ;-) broken:
$ dpkg-query -Wf '${Package}\t${Architecture}\n' libsane-{dev,bin}
libsane-bin i386
libsane-dev amd64
$ sane-config --libs
Package sane-backends was not found in the pkg-config search path.
Perhaps you should add the directory containing `sane-backends.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sane-backends' found
