d736da4208 Elf32, not shared lib: leave alone the hole between .text and .data 
In theory Linux might put pages there (and that would be a problem),
but postpone closing the gap until more experience.

c34fe09a79 Revamp --android-shlib 
Android "Oreo" wants to deal with ElfXX_Shdr[].  So splice 4KiB into PT_LOAD[0]
with an "extra" copy of them.  This requires careful relocation processing.
It also costs a page at run time, and an average of a page in the file
(depending on fragmentation at the boundary between r-x and rw- .)
