Subject: mklib improvements for Solaris
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3cf6e62ae32870d16b2cfc45a37e54a6fb3a1fbe;p=mesa.git

mklib improvements for Solaris

Move flags for linking standard C/C++ libraries from configure.ac to mklib
Use -norunpath flag when linking with Sun C++ compiler
Convert mklib -exports list into a linker mapfile
Set FINAL_LIBS correctly when -noprefix is used
