* Makefile.am (gnumach_LINKFLAGS): New variable.
(gnumach_LINK): Use that one instead of the previously used
`LINKFLAGS_gnumach'.
* i386/Makefrag.am (LINKFLAGS_gnumach): Rename to `gnumach_LINKFLAGS',
move into [PLATFORM_at] and pass `_START'.
* i386/ldscript: Don't hardcode a _start address of 0x100000, but make
it configurable via `_START'.
