s390/vdso: remove -nostdlib compiler flag

Browse Source 
[ Upstream commit 7b737adc10d269e7fdf714ae2caa2281b6a801cf ]

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 2b2a25845d ("s390/vdso: Use $(LD) instead of $(CC) to
link vDSO"), $(LD) is directly used, hence -nostdlib is unneeded.
