Violating US laws make it difficult for you to even stay in the country; let alone citizenship.
If you apply for citizenship in another country your US citizenship is automatically revoked. The US does not recognize dual citizenship. You revoke it in writing at a US embassy, outside the US.

The US recognizes dual citizenship.

I married my Samoan fiancee in 2005. Little did I know he was an overstayer. We thought it would be easy since we were married and all we needed was to file in papers. While the papers were lodged , I realised I was expecting. After three months , immigration authorities surprised us to tears. my husband was deported I screamed telling them that we had a child how could they do this. He said he would wait 5 years and then come. My life has turned upside down. I was told getting a lawyer is expensive and with no guarantee. NZIS do not want overstayers to use marriage as a convenience, so it is painfully hard. Do not marry an overstayer. I will update later.
US citizenship can only be renounced in writing at a US embassy (i.e. outside the U.S.). Be sure you have citizenship in another country before doing this.

If he is a US citizen that happens to be in Turkey, then yes. If he has Turkish citizenship, he will need to attain US citizenship (either dual citizenship or give up his Turkish citizenship for an American one).
If the parents are US citizens, then the child gets duel citizenship (citizenship in the country he/she is born in [depending on local laws], and US citizenship). Any person naturalized in the US or by American parents is a US citizen.
