Running the compilation with DTrace based profiled (instead of
rebuilding with profiling enabled) found the following top CPU
consumers:

__gnat_portable_no_block_spawn                           994414500
system__os_lib__non_blocking_spawn                      1002010800
make__compile_sources__compile.15427                    1010527200
make__compile_sources__start_compile_if_possible.15545       1029687100
namet__name_chars__set_item                             1248495500
snames__initialize                                      1710811700
namet__name_find                                        1750025500

So something strange seems to be happening in gcc/ada/named.adb
(Name_Find).
