Sorry for top-post.
I'm not sure the compiler built(gcc 4.9) by myself is precisely right. The
compiler is built with original gcc 4.5.3 toolchain plus gcc configure to
ease the building of gcc since uclibc has been built.
If you have built this toolchain, would you mind to use
mipsel-linux-readelf -aW one lib built by that toolchain to see whether or
not there is a .rel.plt section? If there is always no .rel.plt section, I
guess this is the MIPS feature for PIC. Many thanks.
I will test android ndk MIPS toochain first, and then build the whole
toolchain myself.
