Current behaviour
building fails during linking CXX executable bitcoin-wallet

Expected behaviour
successful fuzz build.
Steps to reproduce
Using master branch:
cmake -DCMAKE_C_COMPILER=/usr/bin/clang-16 -DCMAKE_CXX_COMPILER=/usr/bin/clang-16 --preset=libfuzzer
Note here I am using clang-16 because the project fails to even begin the build process due to an error: uint256.h:133:19: error: call to consteval function 'util::ConstevalHexDigit' is not a constant expression. After finding the issue: #30947 I set the compiler to clang-16 which begins the build process but fails 28% through.
