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.
