build: Allow disabling maintainer mode This allows make rules for generated build files (i.e. configure, Makefile.in, ... ) to be skipped. This is useful when the source is stored without timestamps (for example in CVS or GIT). When the build rules trigger to regenerate the build files, it tries to use the same autotools version (currently 1.14) as was originally used for the release. Since many of our build machines run Debian Squeeze, they only have autotools 1.11 available and the build fails. Currently, we have to work around this by touching all the generated files before building to avoid triggering the make rule. With this patch, we would be able to just run configure with --disable-maintainer-mode instead. The patch sets the default to enable to not change the default behavior.

Add configure check for _Static_assert() Commit 8efede20ef ("Use _Static_assert") introduced the usage of _Static_assert(). However, _Static_assert() is a fairly new thing, since it was introduced only in gcc 4.6. In order to support older compilers, this patch adds a configure.in test that checks whether _Static_assert() is usable or not, and adjust the behavior of the assert_cc() macro accordingly.

build-sys: try harder to shut up compiler wrt strict-aliasing With -Wstrict-aliasing=2 we get the following warning: libkmod/libkmod-signature.c:124:20: note: in expansion of macro 'get_unaligned' sig_len = be32toh(get_unaligned(&modsig->sig_len)); However there's nothing wrong with it. modsig->sig_len is uint32_t and get_unaligned in this case returns uint32_t. There's notstrict aliasing violation.

Revert "build: enable LTO and _FORTIFY_SOURCE with optimization" This reverts commit 27bcc9111b63e94d091c3fa47e81fe52b806cd3e. Let the distro decide about this flag. It's relatively recent and doesn't work well with gcc 4.[678] making the testsuite to fail.

build: cache modules from playground Now that we are able to build our own test modules, also allow to use cached modules so a) kernel headers are not required and b) distro maintainers are happy. It's still need a "--disable-test-modules" in the configure since the default is enabled. There's no license problems anymore since all modules come from our own repository, we ship the sources and the modules can be easily rebuilt.
