Added documentation about harmless warnings to INSTALL file.

It is not simple to fix build warnings from antlr3.
For now, document them so users know they are safe to ignore.

After configure run the usual make, and if that went well, 'sudo make install'
You may see two kinds of warnings during make.
First, /usr/bin/antlr3 may generate a long series of warnings that
begin like this:
warning(24): template error: context ...
Second, you may see compiler warnings that look like this:
RSPLexer.c: In function `mESCAPED':
RSPLexer.c:2674:16: warning: unused variable `_type' [-Wunused-variable]
ANTLR3_UINT32 _type;
^~~~~
You can safely ignore all of these warnings.
