how to up ALSA in directory

I have embedded Linux 2.6.15.4 and it work on arm based device.

when i compile alsa-lib, alsa_utils I set

perfix = ...la-la-la.../file_system

After that I transfer folder file_system to the device and it become base directory.

It is OK.
But when I run any alsa based program on my device I'v got message that configuration files not found in
...la-la-la.../file_system/config_directory...

On this device I have no ...la-la-la.../file_system directory!

file_system - is base directory.

How can I set that programs searchs configuration files in /config_directory...
not in ...la-la-la.../file_system/config_directory...

P.S.
I can create this path (...la-la-la.../file_system/) on the device but it is stupid solution.
