"illegal instruction" during install of xapian-ruby-bindings (AUR)

Question

In the installation process of xapian-ruby-bindings from aur the command
/usr/bin/ruby -I.libs -I. ${dir}$tst
is run from within a shell script. On my system, it causes an "illegal instruction" error, thus the installation fails.
I read in another thread* that this is somehow related to programs being compiled "for SSE2 or something similar". I do not know anything about that, anyway below is my /proc/cpuinfo

By the way, I also get an "illegal instrucion" error when calling (not installing) the mu** program (installed from AUR). This may or may not be related.

If you think so . . . I did not provide the output deliberately, because it really does not contain anything interesting besides "illegal instruction". Anyway, here are the last lines of the xapian-ruby-bindings build:

"Ungültiger Maschinenbefehl" is german for "illegal instruction". (This one never gets translated, no matter what I do with LC_ALL etc.. I hope you do not mind the other german words—I can run the build again with english language settings if anything is not self-explanatory.)
mu is shorter:
$ mu find bla
Ungültiger Maschinenbefehl
EDIT: Replaced german output by its english equivalent, except for mu's error message, which is german regardless of LC_ALL.
