This bug was fixed in the package lightning-extension - 1.0~b5~hg20110719r7996+nobinonly-0ubuntu2

---------------
lightning-extension (1.0~b5~hg20110719r7996+nobinonly-0ubuntu2) oneiric; urgency=low

  * Fix LP: #809757 - FTBFS on armel. Build with --disable-elf-hack, as it's
    basically a noop on Ubuntu anyway
    - update debian/rules
  * Fix LP: #813776 - maxVersion incorrect. Set to THUNDERBIRD_VERSION rather
    than hardcoding to 5.0.* for now
    - add debian/patches/03_maxversion.patch
    - update debian/patches/series
