linuxloader.bbclass: add musl libc support
Current linuxloader.bbclass does not support musl libc ldso, so add it in. After changing, now the linuxloader function will call a subfunction according to which virtual/libc is being used, glibc or musl, the linuxloader_musl function is made on top of the LDSO macro defined in musl source, by mapping related OE variables to it. Change tested on following machines: "genericx86" "genericx86-64" "beaglebone" "qemumips64" "qemuarm64" "mpc8315e-rdb" "edgerouter" "qemumips" "kc705-microblazeel" - meta-xilinx "qemuppc" (From OE-Core rev: 5d4acaed81a811912e60d85c507bee819623369e) Signed-off-by: Ming Liu <peter.x.liu@external.atlascopco.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
