Hi All,

While building makedumpfile for AARM64 Thunder X2, I am getting this error

cc  -g -O2 -Wall -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE

I googled and found

 endif

After adding this change, no more build error.This change was required
for spac64. So do we need similar changes for AARM64 platform also.
