That would be useful, but I'm afraid it may not be feasible for
executables. The RPATH string is in the .dynstr section, which
precedes text, data, and bss in the address space. If you made the
string longer, it would change the load addresses of text, data, and
bss. But executables don't contain the relocation information needed
for making the necessary adjustments in that case.
