scripts, cc/gcc: do not fail on existing symlinks or build.log
If the user builds a toolchain over an existing one, so, without removing
CT_PREFIX_DIR, the build fails as the symlinks already exist, as does the
build.log.
This can also happen (for build.log) if the user first ran in download-
or extract-only.

17 Thanks, indeed. If we came into "#elif WORDSIZE == 32" block, above
18 condition never be true. So we can just move this statement out of
19 "#if...#elif...#elif...#endif" block. Here is a revised patch.

23 Subject: [PATCH] getdents: Fix mips64 build
25 Some archs (such as mips64) do not have getdents64 syscall but have
26 getdents syscall. Define alias for it.
28 This fixes regression from 0.9.30.1.
31 This is once done by commit e8b1c674. But after the commit 33bcf733
32 ("Use getdents syscall if kernel provide supports for this instead of
33 relying upon getdents64."), if __ASSUME_GETDENTS32_D_TYPE was defined
34 the alias for getdents64 is not defined. The macro
35 __ASSUME_GETDENTS32_D_TYPE had been effectively ignored until 0.9.30.1
36 but the commit 0f0f20ab ("Move kernel-features.h header from the
37 linuxthread directory to a common one...") really enables it.
