libpthread: linuxthreads.old: Allow building for no-legacy-syscalls ABI
Since NPTL port to an ARCH can be non-trivial, we must allow the legacy
pthread lib to be built for the common-generic syscall ABI
Note that only linuxthreads.old is allowed, since "newer" linuxthreads
relies on sysctl which the ABI no longer provides.

libc/statfs64: Skip conversion code for new architectures
Fixes the following tests in LTP
statfs02_64 ( test case #5 )
The purpose of this test is to pass an invalid pointer to the statfs64
syscall and check if the kernel returns EFAULT or not. However,
uClibc creates a new statfs struct which is then passed to the kernel.
As a result of which, the kernel returns 0 because the newly created
statfs structure is valid. But, when copying the contens of the new
pointer to the old userspace one, the uClibc segfauls because the old
pointer is invalid. Old architectures are doomed to suffer by this
problem but new architectures can use the statfs64 syscall directly
so that the userspace pointer is passed directly to the kernel and get
the correct errno at the end.

If we end up doing '#undef __NR_xxx', we don't want to leave the

For example, with the ARM EABI layer, we have a bunch of legacy
syscalls that we define early on and then later undefine (such
as __NR_utime). But we left SYS_utime defined so code that tests
for that define before using it would be broken (since it'd be

dl: fix dlsym lookups with RTLD_NEXT
The current code for dlsym() when invoked with RTLD_NEXT lookup
searches for the module where it's being called from, and executes the
_dl_find_hash only for the next module in the chain. However, if the
looked symbol is not there, the rest of the modules are not checked.
Generally this is not a problem as symbols are merged for the parent
modules; so this affects only RTLD_NEXT.
This patch adds a loop iterating through all the following modules.
