config: Handle dash in library name for AC_LIB_LINKAGEFLAGS_BODY

For a library with dash in the name like yaml-cpp the AC_LIB_LINKAGEFLAGS_BODY
function generates a with_libname_type argument variable name with a dash but
this results in configure error.  Since dashes are not allowed in the variable
name.

This change handles such cases and in case input library for the
AC_LIB_HAVE_LINKFLAGS has dash then it replaces it with the underscore "_".

Example of an error for yaml-cpp library before the change using gcc config
scripts in gdb:
gdb/gdb/configure: line 22868: with_libyaml-cpp_type=auto: command not found

After having underscore for this variable name:

checking whether to use yaml-cpp... yes
checking for libyaml-cpp... yes
checking how to link with libyaml-cpp... -lyaml-cpp

config/ChangeLog:

	* lib-link.m4: Handle dash in the library name for
	AC_LIB_LINKFLAGS_BODY.
