Subject: [PATCH] Put on peril-sensitive sunglasses and risk touching gcc
 related build glue again.  Try and deal with platforms that provide their own
 crtbegin/end asm files (ia64 for example).  crtstuff.c does not actually work
 on ia64 since libgcc.a doesn't have a few key support functions when built on
 ia64 so it is compulsory to use crtbegin.asm and crtend.asm.
