For a typical target system this should be set to "/usr", such that
'make install' will install /usr/include/<header files>.
+config HARDWIRED_ABSPATH
+ string "Hardwire absolute paths into linker scripts"
+ default y
+ help
+ This prepends absolute paths to the libraries mentioned in linker
+ scripts such as libc.so.
+
+ This is a build time optimization. It has no impact on dynamic
+ linking at runtime, which doesn't use linker scripts.
+
+ You must disable this to use uClibc with a relocatable toolchain,
+ such as the prebuilt binary cross compilers at
+ http://uclibc.org/downloads/binaries which may be installed at an
+ arbitrary location (such as in a user's home directory).
+
+ The amount of time saved by this optimization is actually too small to
+ measure. The linker just had to search the library path to find the
+ linker script, so the dentries are cache hot if it has to search the
+ same path again. But it's what glibc does, so we do it too.
