Recipe tries to link against local libraries when activating "postgresql" (Error: "unsafe for cross-compilation")

[GitAnonymous]

When activating support for postgresql:

PACKAGECONFIG_pn-php = "mysql sqlite3 pgsql"

The recipe fails:

ERROR: This autoconf log indicates errors, it looked at host include and/or library paths while determining system capabilities.
Rerun configure task after fixing this. The path was '[...]/edison-src/build/tmp/work/core2-32-poky-linux/php/5.5.24-r0/php-5.5.24'
ERROR: Function failed: do_qa_configure

The reason is that the recipe tries to link against local libraries. "config.log" shows among others the following output:

I posted this already in the official yocto mailing list: https://www.mail-archive.com/yocto@yoctoproject.org/msg24335.html

Operating system is Ubuntu 32 bit as well as Ubuntu 64 bit.

I am willed to fix this but I need some support.
