configure fails to find correct boost_major_version on boost 1.58

[Rainmaker52]

When compiling hamsterdb 2.1.11 on ubuntu 15.10, the configure fails with
checking whether the compiler supports GCC C++ ABI name demangling... yes
checking for Boost headers version >= 1.53.0... yes
checking for Boost's header version...

configure: error: invalid value: boost_major_version=

Boost library is installed (1.58).

I'm not sure where this is going wrong, but $boost_cv_lib_version contains an empty string after the test in configure (around line 17338).

Quick 'n dirty workaround is to manually assign "158" to boost_cv_lib_version after the test.

This allows hamsterdb to compile successfully.

OK, thanks. Will look into it soon-ish.

Fixed by upgrading to a newer boost.m4 file
