--enable-x86-tsc is in there, and configure finds TSC support:

+ ./configure --build=i686-koji-linux-gnu --host=i686-koji-linux-gnu
--target=i686-redhat-linux-gnu --program-prefix= --prefix=/usr
--exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin
--sysconfdir=/etc --datadir=/usr/share
--includedir=/usr/include/xenomai/ --libdir=/usr/lib
--libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib
--mandir=/usr/share/man --infodir=/usr/share/info --enable-x86-tsc
--enable-dlopen-skins --with-testdir=/usr/lib/xenomai
[...]
checking for x86 TSC support... y

Build log follows.  What else can I check?
