crt0 location

["Paulo J. Matos" <paulo@xxxxxxxxxxxxxxx>]

Hi all,

Mostly in my work I have several versions of cross gcc for our own port 
compiled in a directory. When I test the compilers I need to provide a 
libc (usually uclibc) and a crt0. Previously the crt0 was being copied 
to the compiler directory for it to be found however we have made those 
directories read-only. How can I tell GCC during runtime where the 
crt0.o is?

I have found out that -Bdir-to-crt0/ works. I am wondering if this is 
the right option to use or there's a better way?

Cheers,
