Description of problem:
rpmbuild macro %{_sysconfdir} points to /usr/etc because rpm looks for
/usr/lib/rpm/ia32e-linux/macros

Version-Release number of selected component (if applicable):
rpm-4.3.3-13_nonptl
rpm-build-4.3.3-13_nonptl

How reproducible:
always, try to rebuild a src rpm with this macro or:
# rpm --eval %{_sysconfdir}
/usr/etc


Steps to Reproduce:
1. # rpm --eval %{_sysconfdir}
2. /usr/etc
3.
  
Actual results:


Expected results:
/etc

Additional info:
The macro %{_sysconfdir} is defined in a couple of files under /usr/lib/rpm/
always with the filename macros
But here on the 64bit version it tries to open:
open("/usr/lib/rpm/ia32e-linux/macros", O_RDONLY) = -1 ENOENT (No such file or
directory)
so the wrong path /usr/etc from /usr/lib/rpm/macros is used.
I did an strace:
# grep macros strace_rpm
open("/usr/lib/rpm/macros", O_RDONLY)   = 3
read(3, "#/*! \\page config_macros Default"..., 8192) = 8192
open("/usr/lib/rpm/ia32e-linux/macros", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/etc/rpm/macros.jpackage", O_RDONLY) = 3
read(3, "#\n# RPM macros for Java applicat"..., 8192) = 6657
open("/etc/rpm/macros.prelink", O_RDONLY) = 3
open("/etc/rpm/macros.solve", O_RDONLY) = 3
open("/etc/rpm/macros.specspo", O_RDONLY) = 3
open("/etc/rpm/macros.up2date", O_RDONLY) = 3
open("/etc/rpm/macros", O_RDONLY)       = -1 ENOENT (No such file or directory)
open("/etc/rpm/ia32e-linux/macros", O_RDONLY) = -1 ENOENT (No such file or
directory)
stat("/root/.rpmmacros", 0x7fbfffe180)  = -1 ENOENT (No such file or directory)
