This has a marginal effect on the binary size, but it saves a few kilobytes so it might be worth it.

On the negative size, it makes the library we produce larger...

From...

-rw-r--r--. 1 dlemire dlemire 447316 May  4 16:59 build/src/libsimdutf.a

to ...

-rw-r--r--. 1 dlemire dlemire 519332 May  4 17:08 buildstrip/src/libsimdutf.a

So I am not sure it is such win.

-ffunction-sections and -fdata-section will enable the linker to remove any unused sections in the binary that consumes simdutf statically.

This may benefit the end-user of libsimdutf.a more than it does libsimdutf.a itself.

It makes libsimdutf.a larger and it makes the generated binaries slightly smaller.
