Package: libselinux1-dev
Version: 2.0.59-1
Severity: normal
libselinux.pc does not set exec_prefix and this prevents packages that
depend on libselinux1-dev from cross-building correctly, resulting in
missing symbols.
Variable 'exec_prefix' not defined in
'/usr/arm-linux-gnu/lib/pkgconfig/libselinux.pc'
Variable 'exec_prefix' not defined in
'/usr/arm-linux-gnu/lib/pkgconfig/libselinux.pc'
dpkg-cross prepares /usr/arm-linux-gnu/lib/pkgconfig/libselinux.pc
from the libselinux.pc file in libselinux1-dev:

(This is the standard method of changing the prefix for pkg-config).
The problem is that, unlike the other pkgconfig files, there is no exec_prefix
defined in the libselinux.pc file.
e.g.
$ cat /usr/lib/pkgconfig/qof.pc
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
$ cat /usr/lib/pkgconfig/libselinux.pc
prefix=/usr
libdir=/usr/lib
includedir=/usr/include
libselinux.pc needs to define a *variable* exec_prefix:
exec_prefix=${prefix}
This can then be inherited in the cross-builds.
Currently, this causes a build failure in e2fsprogs:
../lib/libblkid.so: undefined reference to `dm_log_init'
../lib/libblkid.so: undefined reference to `dm_task_run'
../lib/libblkid.so: undefined reference to `dm_task_create'
../lib/libblkid.so: undefined reference to `dm_task_get_deps'
../lib/libblkid.so: undefined reference to `dm_task_destroy'
../lib/libblkid.so: undefined reference to `dm_task_get_names'
../lib/libblkid.so: undefined reference to `dm_task_set_name'
../lib/libblkid.so: undefined reference to `dm_task_get_info'
collect2: ld returned 1 exit status
The failure to retrieve data from libselinux.pc in a cross-build
situation causes DEVMAPPER_LIBS to be empty (because pkg-config failed)
