[committed 1/3] MIPS/LD/testsuite: mips-elf-flags: Use `-h' only with `readelf'

[Maciej W. Rozycki]

For the purpose of link-time object compatibility handling verification 
code in the `good_combination' procedure from the `mips-elf-flags.exp' 
test script only examines the `e_flags' member of the ELF file header 
and ignores data from any ELF program or section headers present.  Use 
`readelf -h' rather than `readelf --headers' then to obtain data for 
examination, avoiding unnecessary processing to extract this extraneous 
information.

	* testsuite/ld-mips-elf/mips-elf-flags.exp (good_combination): 
	Use `readelf -h' rather than `readelf --headers'.
