Now I'm seeing this failure:
| ../../../../git/sysdeps/linux-gnu/arm/fetch.c: In function 'arch_elf_init':
| ../../../../git/sysdeps/linux-gnu/arm/fetch.c:101:8: error: 'data' may be used uninitialized in this function [-Werror=maybe-uninitialized]
| if (elf_read_next_uleb128(data, &offset, &tag) < 0
| ^
| cc1: all warnings being treated as errors
| make[4]: *** [fetch.lo] Error 1
| make[4]: *** Waiting for unfinished jobs....
| make[4]: Leaving directory `.../ltrace/1_7.3+gitAUTOINC+01b10e191e-r0/build/sysdeps/linux-gnu/arm'
Possibly caused by using -Os, can you retest with -Os?
