Fix redirect in check-reallocarray (#7) Builds on debian stretch are failing due to: ../scripts/check-reallocarray.sh: 17: ../scripts/check-reallocarray.sh: Syntax error: Bad fd number Fix the redirect of stdout and stderr.

check-reallocarray.sh: Use the same compiler Make does Currently we hardcode "gcc", which means we get a bogus result any time a non-default CC is passed to Make. In fact, it's bogus even when CC is not explicitly set, since Make's default is "cc", which isn't necessarily the same as "gcc". Fix the issue by passing the compiler to use to check-reallocarray.sh.
