Hello,
Debian is pushing more and more PIE builds, so that address
randomization can be done. However, on GNU/Hurd, gdb can't work with
core files from processes running PIE programs, so one has to pass
CFLAGS=-no-pie etc. to be able to debug programs, it'll become more and
more problematic.

I forgot to mention: on Linux, its provided in the core file through an
NT_FILE note.

AFAIK gdb does not use fancy information like file-mapping stuff.
NT_FILE is probably hard to support on the Hurd, since we don't have
a way to go backwards from a memory object port to a file (let alone
a file name).
All GDB needs is to know where the PIE was loaded, so it can find the
DT_DEBUG a
