linkers: Fix for targets with a small-data area
On certain targets (e.g. PowerPC) global data below a certain threshold
(e.g. 8 bytes) may resided in a special memory area, the small-data
area. This allows more efficient load/store operations. Placing such
data into the wrong section (e.g. .rodata) leads to relocation errors
during link-time. See test program libtests/dl02 in the RTEMS
testsuite. Using an array of unspecified size prevents that the
compiler assumes that a certain variable is in the small-data area.
