[Bug 363694] [NEW] firebird 2.1 compiled without stack protector, so UDF open failed

[mmarkk]

Public bug reported:

Binary package hint: firebird2.1-classic

firebird-2.1 classic is compiled with -fno-stack-protector,
so any third-party UDF compiled with default gcc options are not loaded by firebird at runtime.
and firebird said:

-function TANH is not defined
-module name or entrypoint could not be found

i think that

When i compile same UDF source with -fno-stack-protector, udf loads and
work perfectly.

How i guess that:

I wrote simple .c file:
int main()
{
    return 0;
}

and run command:
root# gcc qwe.c rfunc 
/usr/bin/ld: a.out: hidden symbol `__stack_chk_fail_local' in /usr/lib/libc_nonshared.a(stack_chk_fail_local.oS) is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status

Because earlier i reported about very BUGGY stak protector i decide to
off this feature in UDF makefile. and YES! now UDF worked !
