This includes not checking the result of malloc and
using the wrong type in sizeof. Only the latter was
caught by scan-build.
Also use more idiomatic sizeof().

It's possible that the unsigned integer may overflow to zero,
and then we might use zero-allocated memory.
This is incredibly unlikely, and I would even go so far as to say
that this is a false positive. Fix it anyway, to silence this warning:
src/link/patch.c:92:24: warning: Use of zero-allocated memory
stack.buf[stack.size] = value;
~~~~~~~~~~~~~~~~~~~~~ ^
Deal with overflow, and check for zero to get rid of the warning.

Yet another case caught by scan-build:
src/link/patch.c:188:21: warning: Division by zero
value = popRPN() % value;
~~~~~~~~~^~~~~~~
Just copy over the code from the division case, with a few modifications.

It's possible that if the FILE passed to yy_create_buffer is at the
end-of file, there may be a null pointer dereference.
This should hopefully fix that.
Found with clang-tools' scan-build:
src/asm/lexer.c:281:25: warning: Array access (via field 'pBuffer')
results in a null pointer dereference
pBuffer->pBuffer[size] = 0;
~~~~~~~ ^

As 444 and 555 seem to be used for no apparent reason, use the more
conventional 644 and 755.
/man is typically unused or a symlink to /share/man now, so just use
/share/man.
