[PATCH 1/1] add support for debian build profiles

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch adds the bitbake variables DEB_BUILD_PROFILES and
DEB_BUILD_PROFILES_CROSS.
The values of these variables are used to define the DEB_BUILD_PROFILES
environment variable.

When cross-compiling, the DEB_BUILD_PROFILES_CROSS variable is defaulted
to "cross", to be consistent with upstream debian.

+### Introduce debian build profiles
+
+All recipes that inherit from dpkg and dpkg-base can utilize the variables DEB_BUILD_PROFILES and DEB_BUILD_PROFILES_CROSS.
+These variables define the DEB_BUILD_PROFILES environment variable which is available in do_install_builddeps and do_dpkg_build.
+The DEB_BUILD_PROFILES_CROSS bitbake variable is set to "cross" when cross compiling.
