testsuite: mallign: Handle word size of 1 byte
This patch fixes a spurious warning for the pru-unknown-elf target:
gcc/testsuite/gcc.dg/mallign.c:12:27: warning: ignoring return value of 'malloc' declared with attribute 'warn_unused_result' [-Wunused-result]
For 8-bit targets the resulting mask ignores all bits in the value
returned by malloc. Fix by first checking the target word size.
gcc/testsuite/ChangeLog:
* gcc.dg/mallign.c: Skip check if sizeof(word)==1.
