Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: carlos.velasco at nimastelecom dot com

When building glibc 2.17 I stepped into an endless loop building
"misc/bits/syscall.d".

===
Debugging (make -d) shows that loop is caused by a prerequisite:
Prerequisite `/usr/include/stdc-predef.h' is newer than target
`/compile/glibc-build/misc/bits/syscall.d'
The problem is that this header is installed just before making this target:
Invoking recipe from ../Makerules:1072 to update target
`/usr/include/stdc-predef.h'.
/bin/install -c -m 644 ../include/stdc-predef.h /usr/include/stdc-predef.h
So this creates an endless loop.
