toke: fix line parsing on big-endian

Trying to compile openbios on Fedora 22 ppc64, I had the following error:

toke -o QEMU,VGA.bin ~/openbios/drivers/vga.fs
...
Tokenizing  ~/openbios/drivers/vga.fs   Binary output to QEMU,VGA.bin
Warning:  File ~/openbios/drivers/vga.fs, Line 1.  Unterminated comment
Nothing Tokenized.  1 Warning.

This can be reproduced with the fcode-utils examples.

"toke" is parsing the comment line until it finds a '\n'.
The '\n' is stored as a char in a field of an union,
but it is read as a long. It works well on little endian but
not on big endian.
