Subject: man: use BUILD_CC and target include files for configure

The configure script was using the cross-compiler for feature tests,
which fails to execute when the target is different than the host.
Change the script to use the build compiler instead, but use the
target include files to check for the target features.

[YOCTO #9359]

+Use BUILD_CC and target include files for configuration tests.
+If cross-compiling, force pathnames for helper programs, since
+autodiscovery by the configure script will not work.
