OK - I need to check on compatibility between GNU objdump and LLVM objdump.
(since newer Darwin and GCN will be using the latter).

-s might work OK since we only have one section, but -j is problematic wit
different section naming conventions.

corollary: one should not assume that other invocations of objdump in  
configure
are working as expected if the objdump is the LLVM one.
