Package: gcc-4.9
Version: 4.9.2-3
Severity: normal
Tags: patch

gcc 4.9.1-19 removed the top-level option to set no_biarch_libs = yes when building crosscompilers. 

-ifdef DEB_CROSS_NO_BIARCH
-  no_biarch_libs := yes
-endif
+no_biarch_libs :=

Then 4.9.2-2 removed another related stanza
-  ifdef DEB_CROSS_NO_BIARCH
-    biarch64		:= disabled by DEB_CROSS_NO_BIARCH
-    biarch32 		:= disabled by DEB_CROSS_NO_BIARCH
-    biarchn32 		:= disabled by DEB_CROSS_NO_BIARCH
-    biarchx32		:= disabled by DEB_CROSS_NO_BIARCH
-    biarchhf 		:= disabled by DEB_CROSS_NO_BIARCH
-    biarchsf 		:= disabled by DEB_CROSS_NO_BIARCH
-  endif

This code has been present for a long time, was working fine until
its recent removal, and is still used by cross-toolchains built for
debian. This change means that current cross-gcc-4.9-* packages can no
longer build unpatched gcc-4.9 so must carry the attached reversion
patch.

Everyone agrees that building cross packages from unpatched gcc-4.9 is
a worthy goal, so please revert this change.

sure, do your homework and build unmodified multilib enabled packages.
