Alexey Brodkin 29bccd0838 pure-ftpd: disable PIE on ARC
Even though ARC gcc understands "-pie" option and attempts to generate
PIE binaries as of today PIE is not really supported for user-space
applications.

So we disable PIE detection if building for ARC.
That first fixes http://autobuild.buildroot.net/results/57a/57a6180809bc51f7206280533f0b9898ce4cfbb4
and also prevents execution of non-supported PIE binary in runtime.

Interesting enough reported build failure is not directly related to PIE
it looks like if PIE is enabled then successful detection of explicit_bzero()
happens erroneously.

A simple test app that mentions explicit_bzero() while built with
"-pie" gives this output:

arc-linux-gcc test.c -pie

--------------------------------->8-----------------------------

And what's really interesting exist status is 0!:
--------------------------------->8-----------------------------
$ echo $?
0
--------------------------------->8-----------------------------

With removal of "-pie" we're getting expected failure and exist status 1:
--------------------------------->8-----------------------------
$ arc-linux-gcc test.c
/tmp/ccaWbKwc.o: In function `main':
test.c:(.text+0x1c): undefined reference to `explicit_bzero'
collect2: error: ld returned 1 exit status

$ echo $?
1
--------------------------------->8-----------------------------

We'll look into that strange issue separately internally.
I filed internal STAR 9000925001 for that issue.
