musl-gcc: `goldilocks_gen_tables` is not a statically linked executable when `--enable-static` and `--disable-shared` is passed to `./configure`
Created by: odiferousmint
Hello.
Due to goldilocks_gen_tables being a dynamically linked executable, it cannot be executed when compiled with musl-gcc:
$ ./configure --enable-static --disable-shared CC=musl-gcc --host amd64 && make -j2Result:
[...]

cd src && musl-gcc -static -std=c99 -fno-strict-aliasing -pedantic -Wall -Wextra -Werror -Wunreachable-code -Wmissing-declarations -Wunused-function -Wno-overlength-strings -I../src -I../src/include -I../src/public_include -I../src/arch_x86_64 -I../src/include/arch_x86_64 -O2 -maes -ffunction-sections -fdata-sections -fvisibility=hidden -fomit-frame-pointer -fPIC -g -O2 -o goldilocks_gen_tables goldilocks_gen_tables-utils.o goldilocks_gen_tables-goldilocks_gen_tables.o arch_x86_64/goldilocks_gen_tables-f_impl.o goldilocks_gen_tables-f_arithmetic.o goldilocks_gen_tables-f_generic.o goldilocks_gen_tables-goldilocks.o goldilocks_gen_tables-scalar.oIt seems to be the case that if we append -static, everything seems to work, the executable can be executed (it cannot if we omit -static, ldd shows invalid ELF header), and all tests pass.
The issue arises only when CC is set to musl-gcc. It works with gcc.
I apologize for the long title, I could not come up with a shorter one that summarizes the issue. :/
