[krbdev.mit.edu #8254] [PATCH] configure: use appropriate default for krb5_cv_sys_rcdir when cross-compiling

[Paul Fertser via RT]

When cross-compiling, looking at what directories are present on the
build machine makes no sense. Default to the temporary directory as
mandated by the FHS instead.

Hello,

Please consider this to be a bug-report. The problem was discovered
when using this library with OpenWrt (as my build Debian machine has
/var/tmp but OpenWrt target doesn't).
