[Chicken-hackers] "make check" is 40 times slower than "make" (gcc 4.9)

[Sven Hartrumpf]

Hi all.

Some months ago, I stumbled across the fact that "make check" for
chicken takes almost 2 hours with recent gcc versions.
(The build without the check step takes only 2.5 minutes -
very impressive. Measured again today.)
Only one test is the "culprit": the many-arguments test (in its gcc part).
As months passed and no one has complained, I do complain, now :-)
