[9fans] linker bug

[Tim Newsham <newsham@lava.net>]

There appears to be a bug in the linker (at least in kl) when
using the -R flag.  When I specify a value of -R0x4 everything
seems to work fine.  If I specify larger values such as -R0x10,
then occasionally (depending on the size of the text region,
I presume) the emitted binary is incorrect.  For example, if
I have an initialized variable:

    static int x = 0x12345678;

then the address of x (in the symbol table and as referenced
by the instructions) will not line up with the initialized word
that contains the value 0x12345678.

I've stopped using the flag in this way (turns out I didnt need
it after all), so I haven't tracked down the bug any further,
but thought I'd mention it before it bites someone else.
