what is strange is that the file exists:

$ ls -l /tmp/glibc/build/benchtests/bench-timing-type
-rwxr-xr-x 1 zimmerma caramba 35760 Jan 16 07:48 /tmp/glibc/build/benchtests/bench-timing-type

$ file /tmp/glibc/build/benchtests/bench-timing-type
/tmp/glibc/build/benchtests/bench-timing-type: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /tmp/lib/ld-linux-x86-64.so.2, BuildID[sha1]=6eaee68beda7ba9d3a4e7c329d427b5c0676483d, for GNU/Linux 3.2.0, with debug_info, not stripped

however it does not want to run:

$ /tmp/glibc/build/benchtests/bench-timing-type
-bash: /tmp/glibc/build/benchtests/bench-timing-type: No such file or directory

Anyway this does not prevent "make bench" to run.
