perf probe: Check if dwarf_getlocations() is available
If not, tell the user that:
config/Makefile:273: Old libdw.h, finding variables at given 'perf probe' point will not work, install elfutils-devel/libdw-dev >= 0.157
And return -ENOTSUPP in die_get_var_range(), failing features that
need it, like the one pointed out above.
This fixes the build on older systems, such as Ubuntu 12.04.5.
