Fix undefined reference to fmtt::v10::*** when we static build with wasmedge.

LGTM

Has this been tested? What distribution and what package provides static builds of libfmt?
AFAIK, alpine doesn't provide static build of libfmt, and libfmt v10 is only experimental in debian.

@CaptainVincent wasmedge 0.14 need libfmt?

In our CI, there are no tests for Alpine. I have just merged this PR into the main branch, but it has not been released yet. Is Alpine important to you? If so, please open an issue to discuss continuous support for Alpine.

It also only affects static linking.

The particular distro is not very important, but we do use the alpine packages for static linking. In general a test for static linking (regardless of the distribution) and for the standalone feature would be very useful.
