installation of package ecl failed

Package doesn't install on i386 systems under 10.10. The reason is that it builds some code in the postinst script and uses the i486-linux-gnu-gcc compiler (or rather a symlink), which is choosen during package build. After we have dropped i486 support in 10.10 i486-linux-gnu-gcc does not exist anymore, so the invocation fails:

Simple rebuild is enough to make package at least installable again.

TEST CASE:

on i386 system install the ecl package - it will fail with version 10.3.1-2ubuntu2, but will succeed with 10.3.1-2ubuntu2.1

REGRESSION POTENTIAL:

package doesn't even install correctly, regression potential is minimal.
