The -nostdlib option requests the compiler to not use the standard
system startup files or libraries when linking. It is effective only
when $(CC) is used as a linker driver.

Since commit fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of
$(CC) to link VDSO"), $(LD) is directly used, hence -nostdlib is
unneeded.

FWIW, it looks like this has been submitted to RMK's queue:
