makefile: execute a command and grep then awk

CP=cp
LIB_UNIXODBC=/usr/src/tpkgs/unixodbc/2.3.1/linux86w/lib/libodbc.so
RELEASE_DESTDIR=/bld/release/nsr/fb_mssql_linux/linux86w/source


$(CP) $(LIB_UNIXODBC) $(RELEASE_DESTDIR)/ddbda/odbc/$(shell objdump -p $(LIB_UNIXODBC) |grep
'SONAME' |awk -F ' ' '{print $$2}')

which equals to command line:

cp -f /usr/src/tpkgs/unixodbc/2.3.1/linux86w/lib/libodbc.so /bld/release/nsr/fb_mssql_linux/linux86w/source/ddbda/odbc/libodbc.so.2

Note:

1. shell to execute a command in a makefile

2. not like that in bash command line, the grep string is marked with single quotes.

3. there are double '$' in the awk statement.

Problem: sum for each column in a text file(ignoring the first line)

Solution:
cat file |awk -F " " 'function abs(x){return ((x < 0.0) ? -x : x)}NR>1{sum1+=$1; sum2+=abs($2)} END{print sum1;print sum2}'

Example:
$cat file
1000    1000
8       8
2       -2
3       0
7       5

$.my.sh
