Description Josh Triplett 2012-10-05 00:47:47 UTC
If I install intel-gen4asm to a non-standard location (such as /tmp/inst), and configure with PKG_CONFIG_PATH set accordingly (PKG_CONFIG_PATH=/tmp/inst/lib/pkgconfig), configure will find intel-gen4asm, but the make rules that use it will attempt to invoke it without a full path, resulting in a build failure with "intel-gen4asm: command not found".  (Or worse, invoking a version of intel-gen4asm other than the intended version.)  The configure script should record the bin directory from the pkg-config file, and the make rules should invoke intel-gen4asm from the appropriate location.

Also, we shouldn't rebuild the gen4 asm unless explicitly enabled by the developer.

    Use path for intel-gen4asm derived from pkg-config
    As we use pkg-config to determine whether to use intel-gen4asm, we
    should also use it to locate the right version of intel-gen4asm to use.
    This allows the user to install the assembler in a non-standard path for
    cross-builds and similar.
