Subject: tests: Adjust header inclusions and Makefile.test
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c13c73f1ae93c4d33458fa050953d6675f4e269d;p=microwatt.git

tests: Adjust header inclusions and Makefile.test

This fixes the decrementer, illegal and sc tests to compile
successfully with cross-compilers that don't provide unistd.h
or string.h.  Instead of those headers we include stddef.h.

This also fixes tests/Makefile.test to do what one expects
when CROSS_COMPILE is defined in the environment.
