package/uclibc: fix ARC build with 4.x kernel headers

Browse Source 
Provide correct grouping for preprocessor conditions to avoid building
ld.so with undefined macroses which are in use. This is a fix for
package/uclibc/0002-Fix-compilation-with-4.x-kernel-headers.patch.

Subject: [PATCH] [ldso] Group conditions after `&&`
If the conditions are not grouped we can reach
this block even if `__NR_stat` is not defined.
`defined __NR_stat && ((!defined(__UCLIBC_USE_TIME64__) || defined(__sparc__))`
gives us false but `LINUX_VERSION_CODE <= KERNEL_VERSION(5,1,0))`
may give us true. So if linux headers version is below 5.1.0 and
__NR_stat is not defined we can have compilation error
