libixion's configure.ac contains a Bashism (use of == operator with test built-in). Thus, configure emits an error when /bin/sh is not Bash. This doesn't cause the build to fail outright, but it may be causing misdetection of features. AS_IF([test x"$enable_werror" == "xyes"], [ ./configure: 19427: test: xno: unexpected operator Suggest setting CONFIG_SHELL=/bin/bash when running configure. The "unexpected operator" message above is not present when CONFIG_SHELL=/bin/bash.
Upstream patch welcome.
