Fix -pthread issue on lang/gcc3[34]

[Norikatsu Shigemura]

Hi Gerald!

	I have a patch to fix -pthread issue on lang/gcc3[34].

	BEFORE: on 5.2.1 or after
	$ gcc3? -pthread FILE of 'int main(void) { return 0; }'.
	$ ldd a.out
	a.out:
		libc_r.so.1 => /usr/lib/libc_r.so.5 (0x68076000)
		libc.so.6 => /lib/libc.so.6 (0x6809d000)

	AFTER: on 5.2.1 or after
	$ gcc3? -pthread FILE of 'int main(void) { return 0; }'.
	$ ldd a.out
	a.out:
		libpthread.so.1 => /usr/lib/libpthread.so.1 (0x68076000)
		libc.so.6 => /lib/libc.so.6 (0x6809d000)

# Inspired by lang/gcc32, lang/gcc-ooo.

	May I commit this OK?
