Bug 505246

Created attachment 182052 [details]
minimal sample code to reproduce the issue

SUMMARY

trying to use autotools to build a project using `kde-neon-6` plugin / `kf6-core24-sdk`  as libtoolize is not located properly.

STEPS TO REPRODUCE

try to use use `kde-neon-6` with in an autotools project. a minimal sample code is provided in attachment 

OBSERVED RESULT

logs from the command `snapcraft --verbosity verbose build`

Recommended resolution: Check the build output and verify the project can work with the 'autotools' plugin.

Failed to run snapcraft in instance
```

EXPECTED RESULT

either libtoolize should execute properly or kf6-core24-sdk shouldn't ship libtoolize (snapcraft documentation suggest to install the corresponding packages [1])

SOFTWARE/OS VERSIONS

kf6-core24-sdk: 6.11.0-6.2.5-24.12.3
kde-qt6-core24-sdk: 6.8.3
Qt Version: 6.8.3

ADDITIONAL INFORMATION

* overriding the PATH in the build-environment has no effect as the kde-neon-6 extension prepend kf6 paths to the user defined paths

* this can be worked around  by patching libtoolize like it's done for pkg-config files (see [2])

   ` sed -i -e "s#/root/stage#/snap/kf6-core24-sdk/current#" /snap/kf6-core24-sdk/current/usr/bin/libtoolize`

   but this hack can't be done in snapcraft.yaml side as snap/kf6-core24-sdk is readonly. maybe there are some proper way to relocate libtoolize,
