ax_boost*.m4: fix library detection when compiling with -pedantic
When running the Boost macros with the "-pedantic" compiler
switch, they fail. It seems that the problem is a multiply
defined "main" function in the generated test program. I changed
the call to AC_CHECK_LIB to use "exit" instead of "main", which
seems to work reliably.
