Handle this using BUILD_TYPE instead.

This reverts commit 47b5eed7121305d375cfc9a6fd1ba21ff1430130.

Why this source file bothers including <malloc.h> at all (on platforms
where it exists) I have no idea... This is C++ for chrissake. And the
standard C location for the malloc() declaration is <stdlib.h> anyway.

Not needed now with a normal SAL_DLLEXTENSION defined for iOS.

This reverts commit dc915ed7fbbbeef9eefbf5bda07289a9462b6904.

Do it even if it can never be used successfully in an iOS app anyway,
as they are not supposed to load dynamic libraries (except system
ones).

this time run git add before commiting to commit the locally tested
version, and not some intermediate crap that was added in between

and remove *.orig and *.rej files that were committed by accident

Drop the TARGETPLATFORM=BUILD indication of stuff that is to be built
for the build platform. I will handle the split of stuff built for the
build or host platforms differently.

Add explicit rules to do nothing for the cross-compilation case, but
likely even that will be unnecessary in the case of complete modules
like xml2cmp. I will just mark modules that are for the build platform
only with an own flag in BUILD_TYPE.

this fixes the sfx2 subsequenttest
