Subject: [PATCH] MIPS: 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 2ff906994b6c ("MIPS: VDSO: Use $(LD) instead of $(CC) to
link VDSO"), $(LD) is directly used, hence -nostdlib is unneeded.
