  Testing finished.  No regressions, and fixed a bunch of failures on
sh-unknown-pe:

  There was a SEGV in pe-dll.c/generate_reloc(), caused by the global reloc_s
pointer not having been initialised to point to a blank BFD; apparently SH
does use .reloc sections in fully-linked executable images, so it was really
suffering from missing that call to pe_exe_build_sections() that was
needlessly being taken by the x86 and ARM targets instead.  There's still a
load of failures, so I don't know if it's necessarily resolved all the
problems, I'll look a little deeper while I'm respinning the long section
names patch.

  It also fixes the ld-bootstrap "bootstrap" test on Cygwin.

ld/ChangeLog

	* emultempl/pe.em (gld_${EMULATION_NAME}_after_open):  Don't emit
	inadvertent .reloc sections caused by refactoring accident.

  Ok?

    cheers,
