travis ci: enable gcc, call build.sh && test.sh

gcc is default compiler on most distributions, we should
also test with it.

build.sh exists and should be tested as well, so why not use
it in Travis.
test.sh outputs much more details than "make check", so
run it as well.

Additionally, make build.sh and test.sh work when called from
other directories.
