test fails on i386

[daniel-baumann]

Hi,

currently building gocache on i386 fails when running the tests:

[...]
# github.com/TwiN/gocache [github.com/TwiN/gocache.test]
 src/github.com/TwiN/gocache/gocache_bench_test.go:79:66: cannot use 999 * Gigabyte (untyped int constant 1072668082176) as int value in argument to NewCache().WithMaxSize(NoMaxSize).WithMaxMemoryUsage (overflows)
 FAIL	github.com/TwiN/gocache [build failed]
 FAIL
[...]

For the moment, I've opted to completely skipping to run the test-suite on i386 in Debian, however, it would be nice if we could still run (and pass :) it.

Regards,
Daniel
