[Tom Hochstein <tom.hochstein@nxp.com>]

An intermittent failure occurs in libical-native do_compile:

A similar issue is described in a fix for gobject-introspection-native.

https://github.com/openembedded/openembedded-core/commit/d3c48ff7d19e86b2338b1778f9563969bba3d336

The problem was fixed there by setting the environment variable
GI_SCANNER_DISABLE_CACHE to disable the use of $HOME/.cache.

Extend the fix to users of gobject-instropection by promoting the fix
to the bbclass.
