SSE2-CPU required for compiling Ruby 2.1.1 with rvm?

Hi,
I have the following problem with installing Ruby 2.1.1:
when I call `rvm install 2.1.1` on a Debian testing/jessie machine that has an Athlon XP 2600+ processor (no SSE2-support), the compiling process is aborted after a few minutes with the following output:
```bash
carsten@debbie ~ % rvm install 2.1.1
ruby-2.1.1 - #removing src/ruby-2.1.1 - please wait
Searching for binary rubies, this might take some time.
No binary rubies available for: debian/jessie_sid/i386/ruby-2.1.1.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for debian.
Requirements installation successful.

There has been an error while running make. Halting the installation.
```
'Ungültiger Maschinenbefehl (Speicherauszug erstellt)' would be 'Illegal instruction (core dumped)' in English.

Performing the same operation on an Intel Pentium 4 M (SSE2-support) with the same Linux distribution completes without errors. I'm using rvm 1.25.25 (stable) by the way.

Is it possible to work around this issue somehow? I hope I don't have to get a new computer to keep up with current Ruby development...

Regards,
Carsten
