perf uses sscanf extension %as to read and allocate a string in the same
step.  This is a non-standard extension only present in new versions of
glibc.

Replacing the use of sscanf and %as with strtok_r calls in order to
parse a given string into its components.  This is needed in Android
since bionic does not support
%as extension for sscanf.
