Suppress error console output duing configure in case not an ELF file (#729) On Cygwin, MSYS and MinGW readelf is available, but files generated are no ELF files. This results in an Error output on console: 'checking whether .eh_frame section should be read-only... readelf: Error: Not an ELF file - it has the wrong magic bytes at the start yes' With this patch the error output is suppressed resulting in only 'checking whether .eh_frame section should be read-only... yes' Setting of related variables is not changed.
