This fixes a problem seen when accessing function params in systemtap
on certain platforms, due to flaky debuginfo.

Tested on the following machines with various systemtap scripts:

qemuppc
qemuarm
qemux86
qemux86-64
crownbay
nuc

The following changes since commit 005af45191ded6185c618c708181b31281e43092:

  bitbake: fetch2: avoid printing "no checksum" error message twice (2013-12-22 14:29:13 +0000)

In some cases, the debuginfo generated by the compiler is insufficient
for systemtap to figure out function param locations; using -P allows
it to use prologue searching to find the correct locations.

Enable prologue searching in the configuration so the user doesn't
have to specify it manually.

Fixes [YOCTO #5403].
