I would not make it more complicated than necessary. The systems using
libdl probably all have network support and file systems. For them
wasting 64KiB shouldn't be an issue. I would rename the
bsp_section_sdata_bss_maximum_size to something like
bsp_section_use_maximum_sdata_size since it is actually not a size.
Maybe we can simply use:
/*
* Define bsp_section_sdata_fixed_size to set the size of the
small-data area to a fixed size as specified, otherwise the size of the
small-data area is defined by the section content.
*
* bsp_section_sdata_fixed_size = 65536;
*/
