elfutils_0.148.bb: Fix compilation on uclibc
Currently all components of elfutils dont compile with uclibc but elfutils is one part which is needed by other recipes e.g. gcc 4.5 to compile. we make adjustments so that when compiling for uclibc targets it _only_ builds and packages libelf use --enable-uclibc only when building for uclibc targets The supporting patch is also needed for compiling with uclibc to specify -lintl and -luargp on linker commandline Add missing inherit on gettext (From OE-Core rev: e21267f1837b25fec4443dbf4367e501639541bd) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+on uclibc systems libintl and libuargp are separate from libc.
+so they need to be specified on commandline when we use proxy-libintl
+then libintl is a static archive so it should be listed last since
+elfutils does not respect disable-nls we need to link in libintl
+
+We add a new option --enable-uclibc which will be used to control
+the uclibc specific configurations during build.
