openexr-viewers fails to cross build from source for issues related to
its configure script.
The first issue is that it uses AC_PATH_PROG to look up pkg-config. This
is a common mistake as it yields the build architecture pkg-config
rather than the intended host architecture one. Using AC_PATH_TOOL or
better PKG_PROG_PKG_CONFIG fixes that.
Next, the AM_COMPILELINKRUN macro is buggy. All of its invocations share
their enable state via the common variable $enable_programtest. The last
invocation of this macro "wins" the value for all of them. As such the
configure option --disable-openexrctltest given in debian/rules is
ignored. During native builds, the test is performed and yields the
correct result. During cross builds, the test is skipped and the wrong
result is guessed. Unsharing the enabled-variable between macro
invocations fixes this.
Please consider applying the attached patch to fix both of these.
