Description of problem:
I was writing a spec file and i put ./configure in it instead of %configure
because of buffer overflow issues in the application.
Then i noticed rpmbuild runs first %configure , then ./configure which should be
impossible because i never put the %configure line in the .spec file.

So I tried recompiling other rpms and it runs %configure twice!

I'm adding the output of rpmbuild (notice that i run aclocal and autoconf on
purpose). This is the %build section:

%build
aclocal --acdir=`sdl-config --prefix`/share/aclocal
autoconf
# I had some buffer overflow in zsnes having it configured by the %configure script
./configure
make %{?_smp_mflags}
### end of %build section ###

Version-Release number of selected component (if applicable):
4.4.2-15.2

How reproducible:
always

Steps to Reproduce:
1. add ./configure in the spec file instead of %configure
2. rpmbuild will runs %configure then ./configure
