RFR: JDK-8239708 Split basics.m4 into basic.m4 and util.m4

Fri Feb 21 10:39:17 UTC 2020

The file basics.m4 in make/autoconf is mixing two different concerns:

1) Providing utility/helper functions to the rest of the autoconf files

2) Doing basic or initial setup that does not belong elsewhere.

It should be split into two parts, so these different concerns are 
clearly separated.

Furthermore, the naming has not followed our standards. The functions 
are prefixed "BASIC_" but the file is named "basics.m4". I propose to 
keep the prefix and drop the plural "s" from the file name.
