The top of the map file lists, for each object included from an archive,
why that object was included.  The section is headed

"Archive member included because of file (symbol)"

That is where you need to look.

I don't know why you are looking at fstat, earlier you said the problem
was with close.

I think you left out the next line, which would tell you which symbol
caused libc_a-fstartr.o to be included in the link.
