    Use libtool convenience libraries and better "symbol" table.

seems to break the build on sparc:

sdksyms.c:1740: error: ‘sbus_devtable’ undeclared here (not in a function)

The new awk code is not handling:

extern _X_EXPORT struct sbus_devtable {
    int devId;
    int fbType;
    char *promName;
    char *driverName;
    char *descr;
} sbusDeviceTable[];

properly, as it ends up fetching 'sbus_devtable' instead of
'sbusDeviceTable'
