Patch to reverse the commit

After bisecting I found out that the commit 4131ad5db79a016970287282b938ebed2f19bdb3 prevents building the examples.

This is the error message:
"gcc: error: rte_config.h: No such file or directory"

Everything works fine after applying a patch that reverts the mentioned commit.

It might be my mistake but these are the commands that I run from the project's folder:
make config T=x86_64-native-linux-gcc; cd build; make; make -C ../examples/;

This is the full message from bisecting:
"
4131ad5db79a016970287282b938ebed2f19bdb3 is the first bad commit commit 4131ad5db79a016970287282b938ebed2f19bdb3

examples: fix pkg-config detection with older make
Make versions before 4.2 did not have support for the .SHELLSTATUS variable, so use another method to detect shell success.

Fixes 22119c4591a0 ("examples: use pkg-config in makefiles")
