[PATCH 1/2] icu 3.6: dropp apply=yes from path

[Robert Yang]

The "apply=yes" doesn't appear to be necessary, so drop it.

[PATCH 2/2] icu 3.6: do_install failed: Segmentation fault

[Robert Yang]

There is a "Segmentation fault" error when the tmpdir is longer than 470
(or less), this is because it used "char cmd[1024]" which is not enough
for the command line. Allocate a larger memory size should fix this problem.

I've changed the cmd[BUFSIZ] to cmd[2048], which should be enough for us, and
pushed it to the git repo again:

ideally allocating a string on heap and then freeing
it after use would fix this issue once for all.

Thanks Khem, but the problem is that even we use:

void *malloc(size_t size)

We should still use a constant size since the length of the command
is unknown (or not obviously known):

#else
     sprintf(cmd, "%s %s%s -f %s %s %s %s %s",
         make,
         o->install ? "INSTALLTO=" : "",
         o->install ? o->install    : "",
         o->makeFile,
         o->clean   ? "clean"      : "",
         o->rebuild ? "rebuild"    : "",
         o->install ? "install"    : "",
         o->makeArgs);

So I simply increase the size of cmd[] which is a simple fix.

thats the point. Cant you use srtlen(cmd) ?

I'm afraid not, as the code shows below, we should strlen()
each component of the cmd:

     sprintf(cmd, "%s %s%s -f %s %s %s %s %s",
         make,
         o->install ? "INSTALLTO=" : "",
         o->install ? o->install    : "",
         o->makeFile,
         o->clean   ? "clean"      : "",
         o->rebuild ? "rebuild"    : "",
         o->install ? "install"    : "",
         o->makeArgs);

and this is only the part for linux os, it still has similar parts for
U_WINDOWS and OS400 (the component are different), if we strlen() each
one of them, that would make it complicated. the icu pkg does use many
malloc() in the other part of code, but it uses the char array here,
I think that maybe this is the reason.
