Bump to the latest 4.1.7 version and improve the cross-build logic. With the new patches the build is basically architecture-agnostic making it possible to ditch the arch-specific cache to use a generic one. Some toolchains might not be too happy with samba4 because of bitrot, hopefully we'll find and fix or blacklist those with autobuilder help.

Subject: [PATCH 2/5] build: unify and fix endian tests
|
|
|
|
Unify the endian tests out of lib/ccan/wscript into wafsamba since
|
|
they're almost cross-compile friendly.
|
|
While at it fix them to be so by moving the preprocessor directives out
|
|
of main scope since that will fail.
|
|
And keep the WORDS_BIGENDIAN, HAVE_LITTLE_ENDIAN and HAVE_BIG_ENDIAN
|
|
defines separate because of different codebases.
