f481afae53 Make.pkg: remove .so before installing new one 
On Linux, overwriting an mmap'ed file causes
all the MAP_PRIVATE pages to get refreshed
with the new content, even ones that have been
modified by the process that did the mmap.

One specific instance of this is that after the
dynamic linker has relocated a page from a .so,
overwriting the .so will un-relocate it, making
the next use of one of the no-longer-relocated
addresses incorrect and probably crash the
program.

Linux must go out of its way to break programs
in this way: the pages have already been copied
on write, so they're not shared with the file system
cache, and it trashes them anyway.  The manual
says the behavior when the file gets overwritten
is "undefined".  Removing before copy avoids the
undefined behavior.

558477eeb1 fmt: add Errorf helper function 
This crops up in a lot of places.
It's just a one-liner, but doesn't add any dependancies.
Seems worth it.

9ff4565e2b gofmt: stability improvement 
There are a variety of token pairs that if printed
without separating blank may combine into a different
token sequence. Most of these (except for INT + .)
don't happen at the moment due to the spacing
introduced between expression operands. However, this
will prevent errors should the expression spacing
change.
