As suggested by JD, you could try downloading the i386 package for 
compat-gcc-34. You will have to get the rpm manually (eg with wget) 
since it's not in the x86_64 repo. Then try to install it, hopefully any 
deps can be found in the x86_64 centos repos (eg 32-bit versions of 
libgcc and glibc are there).
If it conflicts with 64-bit compat-gcc-34, you can rpm -e this package 
and try again (assuming you only need to compile for 32-bit with gcc34).

Than see if your project builds, and if it does carefully check the 
shared libs with ldd - and test in your embedded system.
Might work, might not. But it will be a lot faster than reinstalling, so 
may be worth a shot.
