Oh I see the confusion.

No, you're absolutely right, liblzma DOES need -lrt.  And indeed, we DO
use pkg-config to get info about liblzma.

And that's why linking of gdb itself succeeds: it links lzma with its
pkg-config options and that causes -lrt to be linked, as a side-effect.

However, I'm whinging about gdbserver (and libinproctrace.so), and
liblzma is not not linked into those, and so neither is -lrt.
