I didn't look much at the patch but noticed it hardcodes i686 as the target. 
Is your system a 32 bit intel system? If no, that might explain what is the 
problem you encounter.

Also you can try playing with the number of / (adding or removing one) in line 
396 of the patch (the one that sets CONFIG_TCC_CRTPREFIX.

I suppose you mean no ld.so. Currently tcc fails to work with -static with 
glibc but I don't know if that is the case with uclibc. I know there is some 
line about uclibc in tcc's code so it should be supported but I never tried.
