There is a bug in how libecc is made. Specifically in the build rules for compiler-rt. Currently compiler-rt is built using the default compiler options in libecc/mkscripts/targets/<target>/setup.mk. These make scripts are obsolete and should be replaced with an appropriate target configuration from libecc/config. All of the other libraries are built with the right config, but unfortunately compiler-rt has a pretty complicated build script and I haven't gotten around to figuring out how to fix it. The ELLCC specific compiler-rt build script is in libecc/src/compiler-rt/make/platform/ellcc_linux.mk.
Resolved as WONTFIX during bug database cleanup.
These bugs are obsolete with the new build and deployment process.
