Subject: [PATCH] sparc: vdso: remove -nostdlib compiler flag

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 3c2b2d9408b1 ("sparc: Really use linker with LDFLAGS."),
$(LD) is directly used, hence -nostdlib is unneeded.
