[patch]: Discard some sections for pe and pep

[Kai Tietz]

Hello all,

we just were falling over the lto sections generated by gcc with lto
support. Those section can be discarded by final linkage AFAIU.
Also this patch ensures, that .bss section is getting aligned to a 16
byte block, this avoids some issues with sse usage.
About the discarding of section .gnu_debuginfo I am not that sure, but
AFAICS it should be ok here, too.

	* scripttempl/pe.sc: (.note.GNU-stack): Mark as discardable.
	(.gnu_debuglink): Likewise.
	(.gnu.lto_*): Likewise.
	(.bss): Use 16 byte alignment.
	* scripttempl/pep.sc: (.note.GNU-stack): Mark as discardable.
	(.gnu_debuglink): Likewise.
	(.gnu.lto_*): Likewise.
	(.bss): Use 16 byte alignment.

Tested for i686-pc-mingw32, i686-pc-cygwin, and x86_64-pc-mingw32. Ok for apply?

Cheers,
Kai
