DESCRIPTION:
Using gcc-6.2.0 to build binutils-2.39 (current maneage 4318670) leads to a
fatal error

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -D_GNU_SOURCE -I. -I./../include
-I./../bfd -I../bfd -DNOBFD=0 -I/BUILD/software/installed/include -std=gnu99

compilation terminated.
make[6]: *** [Makefile:723: libgp_collector_la-jprofile.lo] Error 1

This appears to be the result of trying to build 'gprofng' ("gnu profiler next
generation"), which is in the current version (2.39) of the basic level
package 'binutils', because building gprofng depends on a java header file
'jvmti.h'.

ANALYSIS:
Newer gcc versions apparently find some way of building gprofng without
needing this external java dependence. This is not a solution to the bug,
because we don't want people with an older host gcc version, such as 6.2.0, to
have to downgrade binutils.

PROPOSED FIX:
Based on our reproducibility criteria, favouring builds that work on both
newer and older host systems is a higher priority than enabling fashionable
new tools, especially at the stage of building 'basic' tools. Moreover, even
if some fields of research might use java as a high-level language, profiling
the code does not need to be done within maneage itself.

So the fix proposed here is to disabled the build of 'gprofng' in the build
rule for 'binutils' in 'basic.mk', i.e. by adding '--enable-gprofng=no' to the
build rule. This is implemented in commit c0e30c1 [1].

Users knowing how to do profiling will have the skills to override this build
rule.
