mpers.sh test uses the wrong readelf

I cross-compile from a Debian amd64 bases system to a custom amd64 system. 
During configure I get these warnings:

checking whether mpers.sh -m32 works... readelf: Warning: skipping invalid relocation offset 0x22e in section .debug_info
readelf: Warning: skipping invalid relocation offset 0x23a in section .debug_info
readelf: Warning: skipping invalid relocation offset 0x247 in section .debug_info
readelf: Warning: Invalid pointer size (0) in compunit header, using 4 instead
readelf: Warning: CU at offset 0 contains corrupt or unsupported version number: 588.
readelf: Warning: Invalid pointer size (82) in compunit header, using 4 instead
readelf: Warning: Debug info is corrupted, length of CU at 5 extends beyond end of section (length = 1000002)
cmp: EOF on mpers-m32/sample_struct.h
no

The same happens for -mx32 later. I decided to use the target readelf and 
things went smoother then:

sed "s,^[[:space:]]*readelf ,${target_platform}-readelf ," -i strace/mpers.sh

[…]
checking whether mpers.sh -m32 works... yes
checking for struct stat... yes
checking for struct stat.st_mtime_nsec... yes
checking for struct stat64... yes
checking for struct stat64.st_mtime_nsec... yes

I'm unsure how "correct" either behavior is, but for me it looks sensible to 
use the target readelf on a target binary.

Greetings,

Eike
