lib/oe/qa: ELFFile: check that a path is a file before opening it
When opening an ELF file check that a filename points to a normal file before attempting to open it, as if the file turns out to be something more exotic like a FIFO it could hang forever. (From OE-Core rev: 4b3576bc30d8f8cdcde25189def8b059fc92b27c) (From OE-Core rev: d3af2058e2753516b9aaf7f6d71162363eea11d4) Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
