Bug#853194: libsoxr FTCBFS: aborts on endianess test, runs test suite despite DEB_BUILD_OPTIONS=nocheck

[Helmut Grohne]

Source: libsoxr
Version: 0.1.2-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

libsoxr fails to cross build from source. dh_auto_configure correctly
passes cross compilers to cmake, but cmake fails running the endianess
test. Also the default build target tries to run tests. The attached
patch supplies the endianess test result from DEB_HOST_ARCH_ENDIAN and
correctly handles DEB_BUILD_OPTIONS=nocheck. With the patch, cross
building libsoxr is successful. Please consider applying it after
stretch is released.
