Subject: BUG: $ORIGIN does not seem to work

Hello

On glibc the following:

gcc  -o x -Wl,-rpath='$ORIGIN/lib' x.c -L ./lib -lcrypto

or

gcc  -o x -Wl,-rpath,'$ORIGIN/lib' x.c -L ./lib -lcrypto

Gives me binary with relative library path

ldd x
    linux-vdso.so.1 (0x00007ffcb6bee000)
*    libcrypto.so.1.0.0 => /home/wizard/kal-el/lib/libcrypto.so.1.0.0
(0x00007f0bc3593000)**
*    libc.so.6 => /lib64/libc.so.6 (0x00007f0bc31e2000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00007f0bc2fde000)
    libz.so.1 => /lib64/libz.so.1 (0x00007f0bc2dc7000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f0bc39d2000)

cp -rap kal-el/* batman/
ldd x
    linux-vdso.so.1 (0x00007ffdbf0b6000)
*    libcrypto.so.1.0.0 => /home/wizard/batman/lib/libcrypto.so.1.0.0
(0x00007fb682149000)**
*    libc.so.6 => /lib64/libc.so.6 (0x00007fb681d98000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00007fb681b94000)
    libz.so.1 => /lib64/libz.so.1 (0x00007fb68197d000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fb682588000)


But trying the same with musl does not seem to work?
ldd x
/lib/ld-musl-x86_64.so.1 (0x7f07372e2000)
    libc.so => /lib/ld-musl-x86_64.so.1 (0x7f07372e2000)

and if i remove the -L ./lib from the command it uses system library
gcc  -o x -Wl,-rpath,'$ORIGIN/lib'  x.c   -lcrypto
ldd xx
    /lib/ld-musl-x86_64.so.1 (0x7fdd8618d000)
    libcrypto.so.1.1 => /usr/lib/libcrypto.so.1.1 (0x7fdd85ed7000)
    libc.so => /lib/ld-musl-x86_64.so.1 (0x7fdd8618d000)
