Hi Alfred,
Reading your examples...
1. I’m wondering if we should formalize CROSS_BUILD_TESTING in Makefile.inc1:
188 .if ${MACHINE} == ${TARGET} && ${MACHINE_ARCH} == ${TARGET_ARCH} && !defined(CROSS_BUILD_TESTING)
189 OBJTREE= ${MAKEOBJDIRPREFIX}
190 .else
191 OBJTREE= ${MAKEOBJDIRPREFIX}/${TARGET}.${TARGET_ARCH}
192 .endif
2. MAKEWHATIS seems like it should be added to ITOOLS. Do you agree?
3. Seems like strip should be added to ITOOLS if CROSS_BUILD_TESTING is defined (or at the very least LOCAL_ITOOLS).
4. Why did you need to explicitly define the path to INSTALL?
Thanks!
