mips64el-none-linux-gnu, mabi=3D32, openssl 1.1.1v, gcc 13.3.0

hi,

i noticed today whilst compiling openssl that there is an issue with the=20
-mips16 and -minterlink-mips16 flags.

to be specific, when i use gcc 13.3.0 i have no problem compiling both the
libcrypto/libssl libraries AND the openssl program with these flags (greatly
reducing their size).

i noticed in 14.1.0, the libraries compile fine but the compiler fails to
understand the optimised mips16 symbols when compiling the openssl program,
resulting in a failure.

the log for each build is labelled and provided.=
