Fix building on systems with bash 3.0 and older.

Older versions of bash do not support the concatenation syntax (+=) used
in doltlibtool so replace it with a more compatible equivalent.

This patch has been deployed for some time in Mono and WebKit without
incident and doesn't seem to impact performance.

Fixes freedesktop.org bug #18363
