Okay, a shame. The armv5tel version fails and causes the the armv7hl 
build to abort. armv7hl build passes the armv5tel one, so there is 
something low-level on v5tel.

TL;DR
Work in progress, identified some issues and building with a patched 
spec file for testing. Filed as 
https://bugzilla.redhat.com/show_bug.cgi?id=799153.

Longer version, also available in the BZ:

Errors:
./include/atomic.h: In member function 'size_t ceph::atomic_t::inc()':
./include/atomic.h:40:36: error: 'AO_fetch_and_add1' was not declared in 
this scope
./include/atomic.h: In member function 'size_t ceph::atomic_t::dec()':
./include/atomic.h:43:42: error: 'AO_fetch_and_sub1_write' was not 
declared in this scope
...

The ceph.spec contain a BuildRequires for libatomic_ops-devel, which is 
provided by gc.

AO_fetch_and_add1 is defined in 
usr/include/atomic_ops/sysdeps/gcc/arm.h. That file only does some 
useful stuff for ARMv6 and higher architectures. A possible workaround 
is to define AO_USE_PTHREAD_DEFS and not use the optimised code for 
armv5tel.

An unmodified v7hl-only scratch build failed as well:
- http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=537177

Errors:
/usr/bin/ld: ./.libs/libosdc.a(libcommon_la-ceph_context.o): undefined 
reference to symbol 'sem_post@@GLIBC_2.4'
/usr/bin/ld: note: 'sem_post@@GLIBC_2.4' is defined in DSO 
/lib/libpthread.so.0 so try adding it to the linker command line
/lib/libpthread.so.0: could not read symbols: Invalid operation


I guess that AO_USE_PTHREAD_DEFS should be defined automatically within 
the libatomic_ops-devel package (created from the gc srpm) on < ARMv6. 
It also requires adding -lpthread to LDFLAGS (both armv5tel and 
armv7hl). But a possible workaround like the attached patch may be the 
quicker solution to get ceph built.

A scratch-build with the attached patch will show if I am right or wrong:
