profiling - gprof: use no PIE compiler and linker option
PIE is enabled in the gcc of Debian/stretch by default.
However the gprof in stretch isn't able to produce any
output if PIE is enabled. This is also documented here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854704
Disable PIE for the moment to get some gprof output.
However i'm not able to find out how to disable PIE if
compiling and linking is done in two steps. Therefore this
is just removed.
