Description Rolf Eike Beer 2020-07-29 07:47:06 UTC 
The configure check in 0.180 behind "checking whether the compiler generates build-ids" uses plain readelf, even after it checked for a proper cross-readelf before. It should use that one instead.
Comment 1 Mark Wielaard 2020-07-29 10:20:18 UTC 
You are right. It has been fixed in git already:

commit 9698a399292fbc5e07eac17217af2de8bf5cb4b0
Author: Sergei Trofimovich <slyfox@gentoo.org>

    elfutils/configure.ac: use $READELF, not readelf
    
    Allow user to specify own readelf. Use detected readelf,
    not 'readelf'.
    
    Noticed when was building elfutils on tuple-prefixed toolchain:
    
    ```
    checking whether the compiler generates build-ids...
      ./configure: line 5197: readelf: command not found
    no
    ```
