Add a MULTILIB_INSECURE_INSTALL variable to eclass/multilib-minimal.eclass
Sometimes the "multilib magic header" business is an unwanted
feature. For example, it is infuriating to be forced
to wrap a header file (or, less offensively, but still quite
offensively, to be forced to implement inter-ABI
header-smuggling code) just to appease multilib_check_headers,
in the case where an ABI-specific header triggers a multilib_check_headers
failure.
This provides a frob to turn the whole thing off, collisions be
damned. Arguably, it would be better to have a per-header frob,
as well, but this this is better than nothing and trivial to implement.

+# @ECLASS-VARIABLE: MULTILIB_INSECURE_INSTALL
+# @DEFAULT-UNSET
+# @DESCRIPTION:
+# If set to a nonempty value, multilib-minimal_src_install will not perform
+# automatic checking of headers for inter-ABI conflicts, nor will it automate
+# wrapping of header files. Instead, multilib_src_install pseudophases will
+# run without any special protection and the MULTILIB_WRAPPED_HEADERS array
+# will be ignored.
+# See:

+# @CODE@
+# (or the multilib-build.eclass source itself) for further information about this
+# feature.
