Missing 'pinentry: ' subject prefix. I added it when taking the patch

[PATCH 5/7] apr: Use correct strerror_r implementation based on libc type

[Khem Raj]

musl does not implement GNU extention of strerror_r but XSI compliant
version, therefore add it via a packageconfig to set right variables
during configure to cache the value.

configure detection logic depends on runtime test which will always be
wrong on cross compiles therefore backport a patch to make it possible
to cache the needed configure variable.
