Hi, 
AFAIK , We, in package, enable build with debug (./configure
--enable-debug) to create good debuginfo packages. 
I think when rpmbuild begins do debuginfo packages strips the
binaries . 

For example pngquant.spec

./configure --prefix=%{_prefix} --enable-debug

file /usr/bin/pngquant

/usr/bin/pngquant: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for
GNU/Linux 2.6.32,
BuildID[sha1]=ef857b7ad50d1791a17a46d2a02c6a502bebdaa0, stripped
