Description
If I build b2 with b2
(because I want to cross-compile b2), then I can't install it. This reproduces outside of a cross environment too:
$ b2 b2

At this point there's a freshly built b2
binary at .build/gcc-11/debug/cxxstd-11-iso/threading-multi/b2
.
$ b2 install

Looks like the jamfile hardcodes the location of the bootstrap build:
install b2-engine
: $(SELF)/src/engine/b2$(ext)
Obviously most people will use the bootstrap flow, but if I want a b2 for my cross-compiled target then I should be able to use b2.
