add RISC-v support to recent LAME easyconfigs by removing workaround for finding libncurses

[bedroge]

This workaround would set an environment variable with configure_cmd_prefix, and this is somewhat ugly. It also breaks the config.guess update functionality in the configuremake easyblock, as this will check if configure_command exists, and it will think it doesn't exist if the command includes this environment variable (as it's basically doing os.path.exists("FRONTEND_LDADD='-L${EBROOTNCURSES}/lib' ./configure"). See https://github.com/easybuilders/easybuild-easyblocks/blob/develop/easybuild/easyblocks/generic/configuremake.py#L303. As LAME includes a very old config.guess, it doesn't build on RISC-V this way.

I couldn't reproduce any issues with the workaround removed, and without it LAME would indeed build fine on RISC-V, as the easyblock then does update the config.guess. So I'm proposing that we remove this workaround. If it would still be needed for any reason, we should just set it in (pre)configopts.

Only tried the GCCcore 13.2.0 version on RISC-V, as it doesn't really support older GCC versions.

Looks fine.
