BUG: compile random in lfs mode

randomkit.c uses fopen which requires LFS mode to support larger than 64
bit files on 32 bit systems.
TST: add 32 bit travis tests

Implemented by setting up a chroot in the travis VM and moving all the
test logic, including bento build, to a single script.
This is still reasonable fast, about twice as slow as the normal tests.
When Travis updates to a newer OS it can be replaced by standard cross
compiling.
MAINT: enable verbose bento build
