Fixes clang compiler warnings by adding parentheses:
parse_vdso.c:65:9: warning: using the result of an assignment as a
condition without parentheses [-Wparentheses]
if (g = h & 0xf0000000)
~~^~~~~~~~~~~~~~~~
parse_vdso.c:65:9: note: place parentheses around the assignment to
silence this warning
if (g = h & 0xf0000000)
^
( )
parse_vdso.c:65:9: note: use '==' to turn this assignment into an
equality comparison
if (g = h & 0xf0000000)
^
==
