This looks like a gcc bug, testcase:
$ cat test4.c
int a;
inline void builddircommand(void)
{
a++;
}
int main()
{
builddircommand();
return 0;
}
$ gcc-6 -O2 -Wall test4.c
$ gcc-6 -Os -Wall test4.c
$ gcc -O2 -Wall test4.c
$ gcc -Os -Wall test4.c
/tmp/ccbei4dK.o: In function `main':
test4.c:(.text.startup+0x5): undefined reference to `builddircommand'
collect2: error: ld returned 1 exit status
