-// The testdata/{short,long}.a ELF archive files were produced by:
-//
-// $ echo 'package foo; func F()' > foo.go
-// $ gccgo -c -fgo-pkgpath blah foo.go
-// $ objcopy -j .go_export foo.o foo.gox
-// $ ar q short.a foo.gox
-// $ objcopy -j .go_export foo.o name-longer-than-16-bytes.gox
-// $ ar q long.a name-longer-than-16-bytes.gox
-//
-// The file long.a contains an archive string table.
-//
-// The errors.gox file (an ELF object file) comes from the toolchain's
-// standard library.
