Did you test without setting bsp_section_set_sdata_sbss_size? With 
bsp_section_sdata_sbss_size == 0 the location counter moves backwards here:

. += bsp_section_sdata_sbss_size - (bsp_section_sdata_size + bsp_section_sbss_size);

You set the size for the small data area (name in the ABI documents). It 
includes the .sdata and .sbss input sections and your libdl part.
