bjam is Boost's build tool, so obviously it fails within a bjam
invocation. But basically, you can just try to do a minimal Boost
build, with no sub-option enabled. If that still triggers the infinite
loop with Microblaze gcc, then we don't have any other choice but to
add the BR2_TOOLCHAIN_GCC_HAS_BUG_xyz dependency on BR2_PACKAGE_BOOST
itself, and propagate it to the reverse dependencies.

Have you tried playing around with optimization levels, and see if they
all trigger this issue ? For example instead of using -Os, does the
issue also appear at -O2 ?

Best regards,

Thomas
