#1385 Reproducible build: Don't check for /etc/printcap on the build machine when cross-compiling

[Douglas Royds]

Use AC_CHECK_FILE to set a cached variable instead:

ac_cv_file__etc_printcap

When cross-compiling, this variable should be set to "yes" or "no" as appropriate for the target platform.

This is a bit of a brute-force approach: If you're cross-compiling, you will be forced to set this variable, as no assumption can be made from the build host.

[Bart Van Assche]

Have you considered to remove the HAVE_PRINTCAP macro and to add a runtime check for the /etc/printcap file instead?
