No, neither gcc nor clang seem to support this.

Well, your example is syntactically incorrect. But even with a syntactic
correct version, both gcc and clang seem to be clear that it is not supported:
<source>: In function 'callfoo':
<source>:3:30: error: cannot tail-call: volatile function type
3 | [[gnu::musttail]] return foo();
| ^~~~~
And with clang:
<source>:3:25: error: 'clang::musttail' attribute may not be used with
no-return-attribute functions
3 | [[clang::musttail]] return foo();
| ^
