[Simh] Not compiling through Termux on brand new tablet

[Ray Jewhurst]

First, an explanation, after you gave me the fix, I tried it on my old Tab
4 which is what gave me the linker error so just out of curiosity, I tried
it on the E8 before I returned it and no errors!  For future knowledge, the
linker error is benign on the pdp8 but not on the pdp11 which prevents the
processing of disk images. Sorry about the confusion but now I can run Simh
on a larger screen than my phone. Thanks Mark!
