build: remove call to AC_PREFIX_DEFAULT

Browse Source 
> By default, configure sets the prefix for files it installs to /usr/local.

A call to AC_PREFIX_DEFAULT, just to set the value the same as the
default, would seem unnecessary. Note that the "initialize prefix"
comment dates back to aa6567fe6475d3230c7c745a7ca208735af0c331, prior to
when an autoconf macro was actually being used.

See:
