I tried the following to find the cause for this.

First i added

  pwd
  file strpool

to the do_compile_prepend().

Aftre running

  bitbake libatasmart -c clean
  bitbake libatasmart

i saw

  ERROR: log data follows (/home/sledz/work/HydraIP/OE/tmp.6/work/armv5te-angstrom-linux-gnueabi/libatasmart-0.13-r1/temp/log.do_compile.29576)
  | /home/sledz/work/HydraIP/OE/tmp.6/work/armv5te-angstrom-linux-gnueabi/libatasmart-0.13-r1/git
  | strpool: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped
  ...

Then i called a devshell

  bitbake libatasmart -c devshell

Within it

  > pwd
  /home/sledz/work/HydraIP/OE/tmp.6/work/armv5te-angstrom-linux-gnueabi/libatasmart-0.13-r1/git
  > file strpool
  strpool: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped

So the binary has changed in between.
