* check-guile.in: * test-suite/Makefile.am: * test-suite/test-suite/lib.scm: * benchmark-guile.in: * benchmark-suite/Makefile.am: * benchmark-suite/benchmark-suite/lib.scm: Lower the lib modules in the source tree. This lets us remove top_srcdir and top_builddir from the uninstalled paths. * test-suite/tests/asm-to-bytecode.test: * test-suite/tests/brainfuck.test: * test-suite/tests/compiler.test: * test-suite/tests/ftw.test: * test-suite/tests/gc.test: * test-suite/tests/match.test: * test-suite/tests/rnrs-libraries.test: * test-suite/tests/rnrs-test-a.scm: * test-suite/tests/sxml.match.test: Adapt to not expect that module names be prefixed with "test-suite".
