Hi Simon,

You can build using the "--with-libipt-prefix" option when configuring GDB.

$ gdb/configure --help | grep libipt
  --with-libipt-prefix[=DIR]  search for libipt in DIR/include and DIR/lib
  --without-libipt-prefix     don't search for libipt in includedir and libdir
  --with-libipt-type=TYPE     type of library to search for (auto/static/shared)
