You can link with a .so copy of Python shipped with the GDB installation 
using -Wl,-rpath,$ORIGIN.  Unfortunately multiple levels of shell and 
makefile interpretation make passing that '$' down a pain; at Mentor we 
have a shell variable setting

flags='-Wl,-rpath,'\''\\\$$\$$\\\$$\$$ORIGIN'\''/../'"$pypath"

for this purpose, but the exact levels of quotation required may depend on 
exactly how you pass the linker options when configuring GDB.  See 
<http://sourceware.org/ml/binutils/2009-10/msg00257.html>.
