pkg-config on mac is broken

[guymatz]

Description

pkg-config --libs fortran_stdlib returns:
-L/opt/homebrew/Cellar/fortran-stdlib/0.8.1/lib -lfortran_stdlib -lfortran_stdlib_stats -lfortran_stdlib_system -lfortran_stdlib_stringlist -lfortran_stdlib_specialmatrices -lfortran_stdlib_quadrature -lfortran_stdlib_logger -lfortran_stdlib_linalg_iterative -lfortran_stdlib_io -lfortran_stdlib_hashmaps -lfortran_stdlib_ansi -lfortran_stdlib_sparse -lfortran_stdlib_specialfunctions -lfortran_stdlib_selection -lfortran_stdlib_math -lfortran_stdlib_linalg -lfortran_stdlib_sorting -lfortran_stdlib_bitsets -lfortran_stdlib_lapack_extended -lfortran_stdlib_lapack -lfortran_stdlib_strings -ldl -lm -lfortran_stdlib_intrinsics -lfortran_stdlib_blas /Library/Developer/CommandLineTools/SDKs/MacOSX26.sdk/System/Library/Frameworks/Accelerate.framework -lfortran_stdlib_linalg_core -lfortran_stdlib_hash -lfortran_stdlib_constants -lfortran_stdlib_core -lfortran_stdlib_array

-L is missing for /Library/Developer/CommandLineTools/SDKs/MacOSX26.sdk/System/Library/Frameworks/Accelerate.framework

Expected Behaviour

-L/Library/Developer/CommandLineTools/SDKs/MacOSX26.sdk/System/Library/Frameworks/Accelerate.framework

Version of stdlib

0.8.1

Platform and Architecture

MacOS/Arm

Hi! I'm interested in fixing this.
I've tracked down the root cause to how export_pc.cmake handles absolute .framework paths and I'm preparing a PR with the fix now.
