  This is a more serious reason, I agree. I did not checked (yet) but,
for this library, dropped symbols can be private ones.
  In fact, the ABI comes mostly from the OpenCL norm. The libpocl.so.1
library should never be linked directly (unless an application would
like to use very pocl specific 'functions' (if there are any)).
  Instead, an application should link to the libOpenCL.so library
which is an OpenCL call dispatcher to various OpenCL implementations
(pocl is one). The dispatcher load the implementation(s) with 'dlopen'
from the contents of /etc/OpenCL/vendors/*.icd text files.

  We put the libpocl.so.1 library in $libdir instead of $libdir/pocl
just to avoid a path with the architecture in
/etc/OpenCL/vendors/pocl.icd (we just put "libpocl.so.1" in the text
file) so that multiarch works correctly.

  I just saw an upload of pocl 0.13 has been done by someone else.
I will look at these missing symbols to check if a rename is required
or if they are private ones.

  Many thanks for your input
  Regards,
    Vincent
