So this tells ld where to put lib2.a object files,

> mipsel-linux-gnu-ld -Bstatic -T ./link.xn -o TEST_LINK.elf -Map
> TEST_LINK.map --oformat elf32-tradlittlemips lib2.a

and the above says to extract files from lib2.a if they satisfy
undefined references at the point where lib2.a is searched in the link
process.  That is the way archives work.  You don't have any other
object files or -u command line options, so no undefined symbol
references!  You'll need --whole-archive to have the entire contents
of the archive extracted.
