eglibc-nativesdk: Fix buffer overrun with a relocated SDK
When ld-linux-*.so.2 is relocated to a path that is longer than the
original fixed location, the dynamic loader will crash in open_path
because it implicitly assumes that max_dirnamelen is a fixed size that
never changes.
The allocated buffer will not be large enough to contain the directory
path string which is larger than the fixed location provided at build
time.
