* Bump to 5.27, update meta-data, add x86_gcc2 as 2nd arch.
* Move data/misc/magic.mgc to an arch-independent sub-package.
* Drop explicit call to autoreconf since configure works w/o it.
* Replace $dataDir/ by /system/data/ in man1/file.1, man4/magic.4
and man3/libmagic.3 and also move the latter to file_devel.
Also resync the offsets of the patches of a few other recipes:
* file-2.25
* x265-1.9
* libdvdnav-5.0.3
(Syncing patch offsets is not necessary but it does not hurt either.)
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
* portVersionedName contains the secondary architecture,
so using it means secondary package builds fail.
example: $portVersionedName is libwow_x86-0.0.0 when
doing an x86 build on x86_gcc2
