A 32-bit build of BusyBox using clang segfaulted in the test
"awk assign while assign". Specifically, on line 7 of the test
input where the adjustment of the L.v pointer when the Fields
array was reallocated
L.v += Fields - old_Fields_ptr;
was out by 4 bytes.
Rearrange to code so both gcc and clang generate code that works.
