revision 1.8
date: 2011/06/11 00:57:29;  author: matt;  state: Exp;  lines: +2 -0
If we are compiling -msoft-float, define _SOFT_FLOAT

revision 1.7
date: 2011/03/12 07:57:38;  author: matt;  state: Exp;  lines: +3 -1
Define HAVE_AS_TLS until our build tools figure out how to do it.

revision 1.6
date: 2011/02/25 22:36:10;  author: matt;  state: Exp;  lines: +7 -0
Explicitly make sure TARGET_SECURE_PLT is defined correctly rather than
relying on HAVE_AS_REL16 from "auto-host.h".

revision 1.5
date: 2011/02/10 07:18:29;  author: matt;  state: Exp;  lines: +3 -0
Default NetBSD to -msecure-plt now.
