Log Message:
bitcoin: Drop --std=c++0x

While it's not clear what will happen with older compilers, it's also
not clear what dialect bitcoin is in, and boost (fussy about a recent
compiler) is a dependency, so it's probably academic.  Adding
--std=c++{0x,11} seems to only add a deprecation warning.  Thus, leave
this issue for a future update.
