Add multiarch dirs to linker search path

Browse Source 
By default, tcc search libraries in /lib and /usr/local/lib while crt*.o
files are searched in /usr/lib and ld.so is searched in /lib.
Unfortunetely the path are hardcoded in source code. This patch allow
tcc to look in an other directory and also to look in extra directories.
It's then possible to make tcc search libraries in /lib/x86_64-linux-gnu
and /usr/local/lib/x86_64-linux-gnu while crt*.o files are searched in
/usr/lib/x86_64-linux-gnu and ld.so is searched in
/lib/x86_64-linux-gnu.
