The is a 80 character limit for GPG homedir path length which is projectDir/build/tmp-glibc/.gnupg

If projectDir path length is too long, the build will fail with the following error:
 ...
 ERROR: Nothing PROVIDES 'wrlinux-image-std'
 wrlinux-image-std was skipped: The default GPG_PATH '/xxx/build/tmp-glibc/.gnupg'
 of 82 characters is too long.
 Due to GPG homedir path length limit, please set GPG_PATH shorter than 80 characters

Summary: There were 2 WARNING messages shown.
 Summary: There was 1 ERROR message shown, returning a non-zero exit code.

This limitation should be documented, there are two solutions:
 - make sure that GPG homedir(projectDir/build/tmp-glibc/.gnupg) path length is shorter than 80 characters
 - set GPG_PATH shorter than 80 characters in local.conf
