Is there an easy way to check that version?

debian/rules for the gcc-11-cross-11ubuntu1.3 source package contains:

    VER_BINUTILS   := 2.37-5
    MIN_VER_BINUTILS   := 2.37-5

so in theory it could have been built again 2.37, which is still
sufficiently new.

"dpkg -s gcc-11-arm-linux-gnueabihf" says:

    Depends: [...] binutils-arm-linux-gnueabihf (>= 2.38) [...]

so I guess it was actually built against 2.38, which is OK.

Gr{oetje,eeting}s,
