Setting share-mime-info prefix

[PFJ]

Hi,

I'm trying to build boo inside of mock and it reports a problem when
building (it looks like it is trying to put shared mime info into
${RPM_BUILD_ROOT}/share rather than ${RPM_BUILD_ROOT}/usr/share). What
do I need to do to set the shared mime info prefix to be /usr?

I've tried

export SHARED_MIME_INFO_PREFIX=/usr and a few other variations like
this.

TTFN
