bjam-native: don't do debug builds
Previously this recipe was changed to do debug builds because otherwise insane
warns that the binary is already stripped.
However, debug builds for boost.build also pass -O0. It turns out that given
how large Boost is (or, how bad boost.build is) doing a release build with -O3
knocks a third off the walltime for a Boost package in my test, mainly by reducing
how long it spends deciding that nothing needs to be rebuilt in do_install:
PKG TASK ABSDIFF RELDIFF WALLTIME1 -> WALLTIME2
boost do_install -330.7s -69.2% 477.6s -> 146.9s
boost do_compile -7.1s -2.7% 269.3s -> 262.2s
Replace debug mode with INSANE_SKIP=already-stripped.
