Specifically this fixes /usr/lib/libc.so stripping the paths to the libraries. The reason for this in r266227 was both likely because ld(1) = did not fully respect --sysroot until r291226 and because of the lib32 build. The lib32 build does not use --sysroot into the /usr/lib32 path, rather it only uses -L and -B into the /usr/lib32 path and --sysroot into the normal (64bit) /usr/lib. The _LDSCRIPTROOT was added with the ldscript support in bsd.lib.mk so that it builds a 32-bit-sysrooted pathed ldscript in the object directory and then installs a normal unprefixed version in installworld. This commit also fixes the rebuild during install which was broken in r266227. This commit would break DIRDEPS_BUI= LD build of lib32 but it does not currently have a way to build it anyhow. For example, before this change we had in /usr/lib/libc.so: GROUP ( libc.so.7 libc_nonshared.a libssp_nonshared.a ) Now it is restored to pre-r266227: GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a /usr/lib/libssp_nonshared.a ) The motivation for this is in testing of lld. From emaste: lld does not have built-in search paths (e.g. /lib, /usr/lib) and relie= s on -L arguments passed by the caller. As the linker is nearly always invo= ked from the clang driver this is fine other than the fact that /usr/lib/libc.so is an ldscript that refers to libc.so.7 which is in /lib, not /usr/lib.
