Cross compiling reiserfsprogs-3.6.11

Cross compiling reiserfsprogs-3.6.11

Hi list,

I have downloaded and tried to crosscompile the reiserfsprogs-3.6.11. 
Unfortunatelly, in the config.in is used the macro AC_TRY_RUN which 
prevents it from cross compiling. The attached patch replaces the macro 
and the simple C program for transforming CREDITS file, with a simple 
AWK script.

NOTE: To recreate configure script run autoconf in the reiserfsprogs 
directory.

regards

Vitaly, are you aware that the above is a typo and will not work.

Yes, it was already fixed in 3.6.12-pre1, but anyway thanks a lot.
